Objectives
To make some positive step towards achieving a successful Positron Field Assisted Moderator (PFAM) by carrying out a series of positron annihilation studies on clean intimate metal-semiconductor junctions; to conduct PFAM investigations on the following semiconductor substrates: GaAs, GaP, GaN and SiC possibly using semi-insulating forms or material; to use the most advanced diagnostic positron spectroscopy techniques, including Coincidence Doppler Broadening Spectroscopy (CDBS) to study any adverse positron trapping at the metal-semiconductor interface.
