Growth Features of BiTeSb Films on Polyimide Substrates Obtained by Pulsed Laser Deposition.

Thermoelectric materials in the form of thin films are used to create a wide variety of sensors and devices. The efficiency of these devices depends on the quality and efficiency of the thermoelectric materials obtained in the form of thin films. Earlier, we demonstrated that it is possible to obtain high-performance BiTeSb films less than 1 μm thick on polyimide substrates by using the PLD method, and determined optimal growth conditions.
