Microelectronics Research Group


The Microelectronics Research Group (MRG) is a joint research effort of the Department of Physics and of the Institute of Electronic Structure and Laser (IESL) of the Foundation for Research and Technology – Hellas (FORTH). The group facilities are located in the Physics Department building of the University of Crete, while its multi-million euro infrastructure was mainly provided by FORTH. Moreover, the group is staffed jointly by University of Crete faculty members and IESL/FORTH researchers.

The main objectives of the MRG’s research are:
(i) the development of innovative semiconductor nanostructure/heterostructure materials, devices, and circuits, for high frequency electronics and optoelectronics.
(ii) the accumulation of know-how and training of highly-skilled scientific personnel to support industrial activities in Europe and Greece.

MRG came into being in 1986 with the establishment of a laboratory for the growth of III-V compound semiconductors (arsenides) by Molecular Beam Epitaxy (MBE). Since then it has expanded to MBE growth of wide-bandgap semiconductors (SiC and III-nitrides), to advanced materials characterization, as well as to the design, processing and characterization of semiconductor devices and integrated circuits. It has thus become a complete, diverse, and dynamic compound semiconductor microelectronics group.

Recent and current research efforts of MRG are within the following areas:
(i) GaAs optoelectronics (MBE, III-V/Si integration, tunable laser diodes).
(ii) GaN and related materials and devices (MBE, HFETs, InAlGaN QW heterostructures – lasers).
(iii) SiC microelectronics (Zener and IMPATT diodes, MBE).
(iv) GaAs microwaves (MBE, sensors, RF MEMS, MMICs).
(v) Nanostructures (MBE growth and physics of quantum dots).

To exploit its accumulated expertise, the group has recently launched a microelectronics services activity providing epitaxial wafers, processing and measurements. The latter two are ISO 9001 certified.
