Large-area single crystals

S Nishino, JA Powell, HA Will. Production of large-area single-crystal wafers of cubic SiC for semiconductor devices. Appl Phys Lett 42 460, 1983. 

The silicon wafers used in conventional microelectronics arc fragile, relatively expensive, and their size is limited to that of the single-crystal ingot from which they are cut. In applications where large areas arc required, other materials seem... 

In terms of photoelectrode material quality, single crystals comprise a rational choice since their bulk properties can be controlled better and their influence on cell performance may be evaluated in a rather accurate manner, as being microstruc-turally well-defined solids. However, the cost and convenience of single-crystal preparation are not suited to the practical requirement of cheap device components. Polycrystalline photoelectrodes are advantageous in terms of fabrication cost, ability to prepare large areas in one operation, and material economy.
