Fig. 4From: Ultrathin MEMS thermoelectric generator with Bi2Te3/(Pt, Au) multilayers and Sb2Te3 legsa Band energy diagram of Bi2Te3, Pt, and Au before contact. The band gap, electron affinity, and ionization potential of Bi2Te3 and the work function of Pt and Au are estimated from their bulk values; b Equilibrium band alignment of Bi2Te3 and Pt after contact; c Equilibrium band alignment of Bi2Te3 and Au after contact. No interface defect states are taken into accountBack to article page
