Research output: Contribution to journalArticlepeer-review


A new model has been developed for the interpretation of photo-Hall measurements in semiconductor samples of arbitrary shape and inhomogeneous carrier distributions. The model has been tested for samples of n-type indium antimonide and has yielded new results for the carrier recombination time which was found to increase from 350 ns to 850 ns as the photogenerated population increased from 6*1011 to 4*1013 cm -3. The results are interpreted in terms of a single mid-gap trap.
