Conductance and Capacitance of 6-deg Tilt Boundaries in p-Type InSb

Abstract
Conductance and capacitance measurements on α and β grain boundaries in p‐type indium antimonide are discussed. It is found that the grain boundary barrier is of the order of the band gap, which implies that an inversion layer exists at the boundary. It is further found that the predominant current transport across the boundary is minority carrier flow, in agreement with a model described in a previous publication.
