Experimental observation of oscillations of electronic ultrasound absorption in a semiconductor placed in an alternating field
Mansfel'd G.D., Veretin V.S.
Oscillations and reversal of the sign of the coefficient of electronic absorption of ultrasound of frequency 0.5 and 0.7 GHz was observed experimentally in n-InSb crystals placed in an alternating electric field of frequency 1.8 GHz. The experiments were performed at a temperature 77 К in magnetic fields up to 6 kOe.
