Semiconductor physics: Transport news
John J. Boland1
Abstract
Conventionally, conduction in silicon is enhanced by doping — adding impurities that change the material's electronic structure. But exploiting surface effects in thin silicon films may offer yet other opportunities.
Silicon-based electronics continues to obey the dictum known as Moore's law: that the density of transistors on an integrated circuit — a rough measure of the attainable processing power — doubles about every 18 months. As the size of the smallest features of a device approaches the nanoscale, the electronic properties of the constituent materials are increasingly affected by the surrounding surfaces and interfaces.
