| Date | 1976 |
| Description | Citation typed |
| Citation | Professor Spear is distinguished for his experimental research over a period of nearly two decades on electronic transport in condensed matter, particularly measurements of the drift mobility. His work was the first to establish an activated mobility of polaron type in a molecular crystal (sulphur), and a mobility edge in a non-crystalline material (glow discharge deposited silicon). He has determined the density of states in the gap in this material by field effect measurements and their role in photoconductivity, and has recently shown that, contrary to previous ideas, it can be doped. His work is characterised by high experimental skill, felicitous choice of materials and full theoretical understanding. |
