Non-equilibrium states in Semiconductor

Click For Summary
SUMMARY

Non-equilibrium states in semiconductors occur when electrons gain kinetic energy, allowing them to transition to higher energy levels beyond their stable equilibrium state. This energy can be acquired from external sources like light or ultraviolet radiation, or from internal sources such as collisions with other electrons. Understanding these dynamics is crucial for applications in semiconductor physics and device engineering.

Just to clarify - non equilibrium states in semiconductor means that the semiconductor is affected by external factors such as light?

Yes, but to be more specific a non-equilibrium state happens when an electron gains some kinetic energy and jumps to an energy level that is higher than its stable or eqilibrium state. The electron may gain this energy either from an external source (such as light or UV) or an internal source (collision with other electrons).
