Abstract
Cleaving a TGS crystal in vacuum perpendicular to its ferroelectric axis is supposed to create new surfaces where the discontinuity of the spontaneous polarization is uncompensated. The field effect conductance in thin Te films on TGS surfaces, however, gives no indication for a lack of compensation charge at the cleavage face. It is concluded that electrons must be tunneling between both cleavage faces during their separation.Keywords
