Abstract
The current–voltage characteristic of n‐type GaSb has been measured up to 9 kV/cm at 300 °K, and results for the longitudinal magnetoresistance at 300 °K are given up to 7 kV/cm. The experiments are compared with calculations based on a two‐band model taking into account carrier transfer to higher valleys. Avalanche breakdown is observed at the highest field strength under investigation.
