engineering.nyu.eduvacant spot “hole” is created within the covalent bond between one boron atom and a neighboring Si atom. The holes are considered to be positive charge carriers. When a voltage is applied across the silicon-boron mixture, a hole moves toward the negative voltage end while a neighboring electron fills in its place.

djena.engineering.cornell.eduberg developed the concept of hole (which was implicit in the works of Rudolf Peierls [10]). In 1938 Walter Schot-tky and Neville F. Mott (Nobel Prize in 1977) indepen-dently developed models of the potential barrier and cur-rent flow through a metal-semiconductor junction. A year later Schottky improved his model including the presence
