Synergistic Bi–Te Antisite Defects and Crystalline‐Amorphous Hybrid Structure Enable Record‐High Thermoelectric Performance in Flexible Bi2Te2.7Se0.3 Films

Advanced Energy Materials, EarlyView.
Flexible n‐type Bi2Te3 thin films require improved room‐temperature figure of merit (ZT) and mechanical stability. We show that synergistic Bi–Te antisite tuning and crystalline–amorphous hybridization optimizes carrier concentration, mobility, and phonon scattering.

Investigation of Bi2Te3-Bi2Te3-xSx structures by photovoltage measurements

, 2002
The single-crystal structure of Bi2Te3 -Bi2Te3-xSx with a p-n junction was prepared by the heat treatment of p -Bi2Te3 in sulphur vapors.This structure was characterized by the measurement of the photovoltaic effect. The dependence of the photovoltage at 77 K on the wavelenght shows two speaks at 2.8 um (=0.44 eV) and at 1.9 um (=0.65 eV).
