“…The InP has a distance of 0.254 nm as nearest neighbour and direct band gap energy of 1.344 eV at 300 K [36]. It also has one of the longest-lived optical phonons of any compound with the zinc-blend crystal structure [37]. It was used with indium gallium arsenide to make a record-breaking pseudo-morphic hetero-junction bipolar transistor that could operate at 604 GHz [38].…”

“…Therefore SI InP can be prepared also by co-doping with Ti or Cr and suitable acceptors such as Cd, Hg, Zn or Be in sufficient concentration to compensate fully for residual donor impurities [15,16]. The first prototype particle detectors based on SI InP co-doped with Ti+Mn operating at RT with 60% CCE [17] have been fabricated in our laboratory. Co-doping with Ti+Mn is more suitable than doping with Fe due to the smaller carrier capture-rate of Ti and the gettering effect of Mn, yielding InP of higher purity.…”
