Plotting of bandgaps and band offsets vs. composition and temperature for some III/V-compound semiconductors:
AlGaAs, GaInAs, AlInAs, and AlGaSb.
Help: Select parameters, press a plot-button. Use the mouse for data points and zoom, double click for unzoom. Click on legends for enable/disable.
Copy to clipboard works with modern browsers. Chart creation with plotly.js.
Bandgaps: The temperature dependent band gaps of binary compounds are calculated using the Varshni equation and interpolated using bowing parameters
for ternary alloys.
The material parameteres are taken from [Vurgaftman, Meyer, Ram-Mohan, J. Appl. Phys. 89, 5815 (2001)].
Offsets: The material parameteres are taken from [Adachi - Properties of Semiconductor Alloys, Group-IV, III-V and II-VI Semiconductors (2009)].
