Always calibrate with a known standard (e.g., silicon wafer for AFM, NIST-traceable mirror for ellipsometry). 5. Common Misconceptions (Exam Trap Avoidance) ❌ Wrong: "Electrons orbit nucleus like planets." ✅ Right: Electrons exist as probability clouds (orbitals) with quantized energy.
❌ "Bandgap is the same in all directions." ✅ Right: In many crystals (e.g., silicon), bandgap is indirect → momentum change required → affects LED efficiency.
1. The "Why This Matters" Matrix Before diving into equations, understand where each concept is applied in real engineering.
