In theory, negative refraction for electrons should be easy to observe at PN junctions, but in practice, the band gap voltage causes most electrons to reflect at the junction instead of refract.

What is a P-N Junction? A p-n junction is a fundamental building block of modern electronics, formed by joining together two types of semiconductor materials: p-type (positive) and n-type (negative).

A p-n junction is an interface or boundary between p-type and n-type semiconductor materials within a single semiconductor crystal. The positive (p) side contains excess holes, while the negative (n) ...

This course presents in-depth discussion and analysis of pn junction and metal-semiconductor contacts including equilibrium behavior, current and capacitance responses under bias, breakdown, ...

The PN junction is one of the primary building blocks of semiconductors. A diode (one way valve) is a PN junction with p-type on one side and n-type on the other. When a positive voltage is ...
