AlN:Be

Kuang-Hui Li - June 26, 2017

Could we replace Mg by Be as p-dopant for AlN?

CdTe solar cells

Carlos G Torres - June 26, 2017

My previous research back in Mexico focused on the development of low-cost Cadmium Telluride (CdTe) solar cells. They is considered as thin film technology because the active layers are just a few microns thick. I want to show you a quick overlook of this II-VI device technology.

Rectifying behavior realized without p-n junction

Wenzhe Guo - June 26, 2017

Rectifier is used to convert the alternating current (AC) to direct current (DC), due to rectifying behavior that current increases sharply in the condition of forward bias, whereas little current flows in the reverse bias, as shown in Figure 1[1]. At present, solid-state electronic devices with rectifying behavior are mostly achieved by the incorporation of conventional p-n junction that requires doping technology. However, without doping technology to form p-n diode, the rectifying behavior still could come out of electronic devices, like magnetic tunnel junction, molecule diode.
