Band Diagram of p-PbTe/n-Si Heterostructure


In the present work, the energy band diagram of p-PbTe/n-Si heterojunctions made by thermal evaporation of a polycrystalline PbTe layer deposited on a monocrystalline Silicon substrate is constructed. Based on I-V and C-V measurements, the band offsets ΔEC and ΔEV are found experimentally to be 270mV and 610mV respectively at 300K.
