Transparent conducting p-type thin films of c-axis self-oriented Bi2Sr2Co2Oy with high figure of merit†
Abstract
Transparent conducting p-type Bi2Sr2Co2Oy thin films have been first grown on SrTiO3 substrates by a chemical solution deposition, showing c-axis self-orientation. The figure of merit can reach as high as 800 MΩ−1, which is the highest value for p-type transparent conducting thin films by solution methods.
