Periodic Interface Engineering in BN-Modified Bi2Te2.7Se0.3 Thin Films for Enhanced Thermoelectric Transport.
Optimizing thermoelectric transport in Bi2Te3-based thin films requires effective modulation of phonon scattering without severely compromising electronic conductivity. Here, we address this challenge using a periodically modulated architecture composed of alternating pristine Bi2Te2.7Se0.3 (BTS) and BN-modified BTS la...
