Semiconductor Band Parameters
The following data and plots were developed to help me easily distinguish what semiconductor materials may be suitable for different device applications. I have not created this data, but rather compiled it from various references and put it in a form that I find most useful. Hopefully, you too will find it useful.[Kind regards to Jean-luc Doumont for inspiring me to create plots that are easier to read than many you may find out there. All scientists/engineers should read his book, Trees, Maps, and Theorems.]
All data and graphics (plots) may be downloaded for personal use only. Feel free to use them in your own presentations and such. I just ask that you give some reference to this site. But, don’t go publishing them without letting me know. That’s just wrong.

The data has been collected from several references, as outlined below. The Excel spreadsheet also lists these. The primary parameters I have compiled are lattice constant, thermal expansion coefficient, band gaps for each of the three conduction band valleys (Γ, L, and X), Varshni Parameters (both α and β), and bowing parameters for both lattice constant and band gap of the ternary alloys. I do not have data for all materials, but as many as I could readily find. The materials include III-Vs (AlSb, AlAs, GaP, AlP, GaAs, InAs, InP, GaSb, InSb, GaN, AlN, InN), IVs (Diamond, Si, Ge, 3C-SiC, 6H-SiC), and II-VIs (BeTe, BeS, BeSe, MgS, MgSe, MgTe, HgS, HgSe, HgTe, ZnSe, ZnTe, ZnS, CdS, CdSe, and CdTe). Data for the following alloys are also included: SiGe, AlGaAs, InGaAs, AlInAs, GaInP, AlInP, AlGaP, GaInSb, AlInSb, AlGaSb, GaAsSb, InAsSb, AlAsSb, GaAsP, InAsP, AlAsP, GaPSb, AlPSb, InGaN, AlGaN, AlInN, CdSeTe, CdSSe, CdSTe, CdZnS, CdZnSe, CdZnTe, MgZnSe, MgZnTe, ZnSeTe, ZnSSe, ZnSTe, BeZnSe, CdHgTe, MgZnS, ZnHgS, CdHgS, BeCdSe, MgCdSe, CdHgSe, BeZnTe, MgCdTe, ZnHgTe.
