The SEM has been used as a voltage measuring probe to obtain voltage distributions in X-band n+-n-n+ mesa structure Gunn devices. Dynamic distributions are obtained by operating the instrument in the stroboscopc mode. The results show accumulation layers in the oscillating device and the amplifier mode has a high field anode region.
