Semiconductor Physics & Device Technologies
Device physics, junctions, transistors, compound semiconductors, wide-bandgap devices, scaling and reliability.
Build the device-level foundation for the division: how crystal structure, energy bands, carriers, junctions and field-effect structures become real electronic devices.
Technical coverage
The Level-2 index stays visual and navigable; its six Level-3 technical pages now carry a real Phase 3A engineering baseline with controlled source lanes.
Crystal & Band Structure
Crystal lattices, energy bands, bandgaps, density of states and the material foundations that set electronic behavior.
