The achievement of extrinsic doping in to n-type as well as p-type conductivity in ZnO is a challenging task. So far, the fabrication of ZnO based P-N thermoelectric device is not yet realized. This work deals with the deposition and optimization of extrinsically doped n-type ZnO:Al and p-type ZnO:N and their fabrication in to P-N junction thermoelectric device using modified pulsed spray pyrolysis.
The present invention generally relates to a method of preparation of thermoelectric compound. More particularly the present invention relates to a process of synthesis of Morphologically controlled growth of Selenium doped n-type Bismuth Telluride (Bi2Te3-xSex) hexagonal nanoplatelets with an achievement of lowest lattice thermal conductivity and product thereof for fabrication of high efficiency thermoelectric devices.
