Bi2Si2Te6, a 2D compound, is a direct band gap semiconductor with an optical band gap of 0.25 eV, and is a promising thermoelec-tric material. Single-phase Bi2Si2Te6 is prepared by a scalable ball-milling and annealing process and the highly densified polycrys-talline samples are prepared by spark p...
