The photo-Hall technique has been used to investigate the properties of the InSb optical absorption band-edge. An accurate theoretical explanation of the linear absorption results is given, together with new data on the nonlinear aspects of the band-tail. A value of 1.1 x 10-18 for a has been calculated by monitoring the carrier generation during bistability.
Measurements of the intrinsic emittance and response time of a Cs3Sb photocathode are presented. The emittance is obtained with a solenoid scan technique using a high voltage dc photoemission gun. Photoemission response time is evaluated using a RF deflecting cavity synchronized to a picosecond laser pulse train. We find that Cs3Sb has both small mean transverse energy, 1606 10 meV at 532 nm la...
