Semiconductor Device Group

The Semiconductor Device Group undertakes research in a wide range of areas including quantum technology, nanofabrication, silicon germanium (SiGe), nanoelectronic silicon devices, silicon photonics, MEMS, resonant tunnelling diodes, inorganic molecular electronics, thermoelectrics and autonomous sensors. The group is part of the Electronics and Nanoscale Engineering Division in the School of Engineering. The group is led by Douglas Paul and was formed in 2007 when Prof Paul moved from the Cavendish Laboratory in the University of Cambridge to take up a chair at the University of Glasgow.

The Semiconductor Device group is a major user of the James Watt Nanofabrication Centre and also heavily uses the dc to 1.15 THz S-parameter test probe stations and photonic test systems. The group has well equipped electrical and optical test and characterisation facilities with over £2.2M of equipment plus access to another £8M shared between researchers. Below is a list of specific scientific equipment the group has for undertaking research.
