Ultrafast Systems

Dr Khaled Elgaid, Dr David Moran, Dr Xu Li, Professor Iain Thayne, Dr Edward Wasige

The Ultrafast Systems Group conducts research into advanced semiconductor transistor design; ultra-high frequency and ultra-low power monolithic integrated circuit design; manufacture of transistors and integrated circuits with critical dimensions below 50 nm; and broadband on-wafer component test and measurement

Our work has applications in areas including III-V MOSFETs for digital circuits beyond the ITRS 22 nm technology generation; ultra-low power radio transceiver design and realisation for autonomous distributed sensor networks at 6 GHz and 24 GHz; and low noise mm-wave receiver design and realisation for 94 GHz and beyond imaging and sensing.

To be fully exploited, these application areas require low cost, high performance electronic components based on advanced, manufacturable transistor and integrated circuit technologies.  We are addressing these issues by developing GaAs and InP HEMT and MOSFET technologies with gate lengths down to 15 nm.  These next generation transistor technologies will eventually supersede our current monolithic integrated circuits based on 50 nm gate length transistor technologies operating from 6 GHz to 200 GHz.

Nano-Electronic Diamond Devices and Systems

Dr David Moran

Beyond its allure as a rare gemstone, diamond possesses several unique and extreme properties which make it highly desirable as an engineering material for the development of a range of new and exciting technologies.  It has the highest thermal conductivity of any bulk solid which allows heat to flow through diamond easier than any other material. It also has a large electronic bandgap of 5.5 eV which allows diamond to tolerate high electric fields/ high voltage operation and potentially be used in hazardous and radiation intense environments. Diamond also has high intrinsic electron and hole mobility which allows electronic charge to travel through the diamond structure with relative ease, making it ideal for high frequency electronics.

The Nano-Electronic Diamond Devices and Systems group (http://nedds.co.uk/) specialises in the investigation of diamond for the development of various electronic and nano-scale applications. Our current areas of research include diamond transistors (FETs), high power diamond electronic components, diamond nano-imprinting, diamond micro and nano-electromechanical systems (NEMS & MEMS), and diamond based chemical and biological sensors.

Microsystem Technology

The Microsystem Technology Group researches and develops a wide range of leading-edge technologies including combined electronic sensor and imaging systems; medical diagnostic devices; integrated single-chip CMOS sensor devices; sensor and imaging arrays; wireless sensors; terahertz technology and systems; and control and data processing of hardware and software for sensor systems.

Our research work makes full use of the analogue/digital/mixed signal VLSI design and test facilities of the Glasgow Electronics Design Centre, and the custom device fabrication facilities of the James Watt Nanofabrication Centre. We collaborate extensively with engineers, biotechnologists, medics, vets, and computer scientists at a number of other UK and overseas universities. We are also supported by a number of leading multinational companies. Our work continues to attract extensive funding and support from both government research bodies and leading electronics companies.

High Frequency Electronics

Dr Sung-Jin Cho, Dr Jue Wang, Dr Edward Wasige

Research in the High Frequency Electronics (HFE) Group at the University of Glasgow focuses on advanced electronic device technologies and associated integrated circuit design for the microwave, millimeterwave and terahertz (THz) frequency bands, and the integration of these with other physical domains to achieve new system functionality. Presently, we are developing new types of gallium nitride (GaN) based transistors for power electronics and for radio frequency (RF) applications, with funding from the UK Ministry of Defence (MoD), Defence Science and Technology Laboratory (DSTL), for the development of GaN based microwave power amplifiers (contract DSTLX-1000064098) and from the Engineering and Physical Sciences Research Council (EPSRC) for GaN based energy efficient power devices (grant EP/K014471/1). We are also developing compact electronic THz sources based on resonant tunneling diode technology with EPSRC-funding (grant EP/J019747/1). All our fabrication is carried out in the James Watt Nanofabrication Centre (JWNC), while all device/circuit characterisation within the Electronic Design Centre. The group works in collaboration with several academic and industrial partners.

Bendable Electronics and Sensing Technologies (BEST)

Professor Ravinder Dahiya

The BEST group's multidisciplinary research interests include Flexible and Printable Electronics, Electronic Skin, Robotic Tactile Sensing, and Micro/Macroelectronics and System Integration.

The group focus on developing high-performance and cost-effective electronics and sensing systems on flexible substrates to enable tools, such as electronic skin (also known as tactile skin, smart skin or synthetic skin), which is of burgeoning interest in robotics, prosthetics, healthcare, wearable systems, and surgical instruments. Through integration of different types of sensors and electronics on flexible substrates, the electronic skin concept can also be extended to many other applications such as rollable sheets of solar cells or bendable photonics.

Atomic Force Microscopy

Dr Phil Dobson, Professor Jonathan Weaver

The AFM and Hyperlithography group builds on long-standing expertise at Glasgow in the area of electron-beam lithography.

The first strand of the work is concerned with the functionalisation of AFM probes. In this work, the AFM itself is used primarily as a vehicle to allow a lithographically defined sensor to be positioned close to, or in contact with a sample. Using this technique many contrast modes can be devised by simply choosing the sensor type to be made.

Hyperlithography is concerned with the desire to drive the size of structures down to the level at which lithographic objects become commensurate with natural objects, such as large molecules, typical of biological systems. The resolution of conventional electron-beam lithography is typically around 10nm for an isolated shape. Our hyperlithography allows the definition of very small gaps and wires, with significant dimensions down to 1nm or below. Using this capability we are working towards new sensors and instruments.

Magnetoelectronics

Dr Hadi Heidari

The Magnetoelectronics lab aims to promote and support engineering and physical science research in magnetism, magnetic sensors, circuits, devices and spintronics. Research in magnetism is broad ranging from theoretical, simulation, design and experimental work in fundamental physics to applications of magnetic devices, sensors and electronics.

We are working on sensors compatible with CMOS IC technology, allowing them to be manufactured with integrated electronic readout, produced in mass quantities (potentially at low cost), and deployed in a one-time use, disposable format for point-of-care testing. In this regard, various magnetic sensors including Hall effect sensors, Giant Magnetoresistance (GMR), Anisotropic magnetoresistance (AMR), Tunnelling magnetoresistance (TMR), spin valve sensors, SQUID sensors, magnetic resonance sensors (NMR, ESR etc.). Furthermore, we research on the magnetic tweezing to trap and manipulate the magnetic tags with a magnetic field to potentially speed up the reaction or remove unbound tags. Our study also focuses on in-depth analysis using simulation as it’s essential to ensure the correct targeted functionality.
