AWARDS...

Prof Michael Johnston was awarded the Harrie Massey Medal and Prize last December, for his significant contributions to semiconductor physics which, together with materials design, growth and spectroscopic analysis, have led to notable advances in the fields of optoelectronics, photonics and high frequency electronics. This is a medal from the Institute of Physics which is awarded in conjunction with the Australian Institute of Physics.

Prof Laura Herz was awarded the IoP’s Nevill Mott Prof Pat Irwin (centre holding the award), Dr Simon Calcutt, Prof Peter Medal and Prize for her ground-breaking research Read, Dr Fred Taylor, Prof Neil Bowles and the UK Cassini team were into the fundamental mechanisms underpinning light awarded the Sir Arthur Clarke Space Achievement Award for harvesting, energy conversion and charge conduction in Academic Research by the British Interplanetary Society. semiconducting materials.
