Make sure you label the question number clearly. FRQ#4: Heterojunctions (11 points) (1) The band gaps of CdSe and CdTe are 1.70 eV and 1.56 eV, respectively. Their electron affinities are 4.95 eV and 4.28 eV, respectively. Please calculate the valence and conduction band offsets at the CdSe/CdTe heterojunction using Anderson’s Electron Affinity Rule, and identify the type of band alignment for this heterojunction. (6 points) (2) The AlAs/GaAs heterojunction, a Type I heterojunction (the bandgaps are 2.17 eV and 1.42 eV for AlAs and GaAs, respectively), is probably the most widely studied semiconductor heterojunction because of the close matching of their lattice constants. An application of this heterojunction is in modulation-doped field-effect transistors (MODFETs), which are also called high electron mobility transistors (HEMTs). Please explain what modulation doping is and how it leads to much higher electron mobility than what obtainable in a standalone n-doped GaAs layer. (5 points)
