Abstract: Large‐scale multi‐heterostructure and optimal band alignment are significantly challenging but vital for photoelectrochemical (PEC)‐type photodetector and water splitting. Herein, the centimeter‐scale bismuth chalcogenides‐based cascade heterostructure is successfully synthesized by a sequential vapor phase deposition method.… read more here.

Abstract: Abstract To assess the performance of thermoelectric devices with nanostructured materials at high operating temperatures, we investigated the effects of structural changes on the thermoelectric properties of nanocrystalline bismuth telluride (Bi2Te3)/bismuth selenide (Bi2Se3) multilayer thin… read more here.
