Abstract:
1. A complementary doping method, comprising: providing a thin film of a semiconductor or semimetal disposed on a substrate; disposing a dopant source on a surface of the thin film of the semiconductor or semimetal; wherein the disposing does not include implantation or diffusion of the dopant source; inducing a first chemical reaction at a first energy in at least a first portion of the dopant source effective to introduce an n-type dopant, a p-type dopant, or both to the at least the first portion of the thin film of the semiconductor or semimetal; and inducing a second chemical reaction at a second energy in at least a second portion of the dopant source effective to introduce an n-type dopant, a p-type dopant, or both to the at least the second portion of the surface of the thin film of the semiconductor or semimetal; wherein the first and second chemical reaction are effective to produce at least one n-type and at least one p-type region on the surface of the thin film of the semiconductor or semimetal.
