Experimental proof of the multivalued Sasaki effect in n-Si

Abstract
The existence of transverse electric fields on account of a multivalued redistribution of electrons between valleys situated symmetrically to a heating electric field is investigated for n-Si at liquid neon temperature. The transverse voltage appears when the heating field exceeds a certain value of about 8 kV m-1, at least in a part of the sample, and saturates for higher fields applied. It can be switched by magnetic fields of only some 10-3 T, characteristic for a domain formation in the sample with respect to the transverse field.
