Departures from the ideal chemical and physical structure of a semiconductor considered in relation to chemical reactivity

Abstract

Treating semiconductors and similar substances, the paper will discuss chemical bonding in the bulk of the crystals and its modification in the surface regions. It will seek to relate these considerations to the observed physical and chemical properties of the substances discussed.

Electron Diffraction in Surface Chemistry

“…The difficulties to be met in structure analysis are presented in articles by Lander and Morrison (95,99,101), Bauer (6), Khan, Hobson, and Armstrong (88), Tucker (772, 173), MacRae and Gobeli (124), and Lander (92,93). Earlier theoretical papers have also been written (49,89,90,110,142,147,168). Possible complications abound.…”
