ICD - OMNIPRESENT YET INVISIBLE

Walk around. Observe everything. Pay attention to all those remarkable little and big things. Amaze yourself with all those utilities, appliances, gadgets and machines around, many of them communicating with others or just communicating inside themselves in some – for most of us – mysterious way. Imagine that all those appliances and things that come with a battery or main cord fail to work. Maybe due to some power failure, maybe just because they’re on strike. Just try to imagine what still works. That’s not so much. No cars that were build in the past 20 years would run. No radios, no lights, no TV, no automatic doors, no phone, no cell phone, no remote control, no fridge nor microwave, no mp3 player, no heating, no internet… hardly anything would be operational anymore. And that’s basically because most of the things that we use and see are packed with electronic systems. Most of these electronic systems are very small Integrated Circuits (ICs) or chips, largely invisible for most people, but present in and around almost everything we use.

At the IC-Design group (https://www.utwente.nl/ewi/icd) the research focuses on the evolution in integrated electronics, with occasionally revolutionary steps. IC-component sizes are nowadays a fraction of the wavelength of visible light: true nanotechnology! We exploit the most advanced nanometer IC-technologies in the world with focus on CMOS, and hence have many contacts and research contracts with major European, American and Asian players in the field. ICD research aims at creating technological breakthroughs in electronic circuit and system design, leading to higher performance, new functionality and lower power consumption, enabling new possibilities and new applications. In this creative research process, we strive to find fundamental solutions that are widely applicable. Our approach requires a solid theoretical background, good analytical skills, and last but not least creativity: all spear points in the education and research program at ICD.

Our research field ranges from small analog and digital circuits through complex mixed-signal systems like analog-digital converters and RF-frontend circuits to high level electronic system design. Signal frequencies may range from DC to several GHz, spanning almost all relevant circuits and systems in mainstream IC-technologies. Examples of these include wireless radio circuits and systems, AD/DA converters, frequency synthesizers, filters or cancellers for interference and noise reduction, accurate Voltage and frequency references, high speed fiber-optic interfaces, and multi-antenna transceiver systems with microwave integration.

IMS - INORGANIC MATERIALS SCIENCE

The IMS group works at the international forefront of materials science research on complex metal oxides and hybrids, and provides an environment where young researchers and students are stimulated to excel in this field. The research is focussed on the following activities:

Nanoelectronic Materials
The general objective of the chair NanoElectronic Materials (NEM) is the research in new inorganic materials for applications in nanotechnology, and to improve the existing ones. The research is based on current trends in nanomaterials science and developments within MESA+: controlled growth of materials, control of their structure, and understanding of the structure-property relations. Physics Of Complex Inorganic Nano-Materials. The research in the IMS workgroup headed by dr. Gertjan Koster focuses on three areas: manipulated oxide thin film growth and modeling, oxide thin film meso materials and in situ spectroscopy. The research is centered on the COMAT system; a UHV pulsed laser deposition (PLD) system with in situ spectroscopies and imaging techniques (XPS, UPS, XPD, STM, AFM, PFM).

Inorganic & Hybrid Nanomaterials Chemistry
Activities are focused on the development functional inorganic and hybrid nanomaterials and nanostructures from colloidal and chemical solutions. The main emphasis within the research is on oxide and hybrid thin films for energy and electronic applications, soft lithographic micro- and nanopatterning of functional oxides, and the synthesis and applications of low-dimensional nanostructures like nanowires and nanosheets.

Nanomaterials for Energy Conversion and Storage
The research is focused on the study of novel nanostructured thin films with special structural and advanced functional properties at the incorporated interfaces. The aim is to develop new materials towards improved energy applications, such as solid-state batteries and thermoelectric energy generators.
