Spontaneous photon emission from a semiconductor

TL;DR

This paper investigates how external magnetic fields induce spontaneous photon emission in semiconductors by altering their energy bands, providing theoretical calculations of emission rates and spectra that can be experimentally verified.

Contribution

It introduces a theoretical framework linking magnetic field-induced energy band changes to spontaneous photon emission in semiconductors, with detailed calculations of emission characteristics.

Findings

Magnetic fields cause energy band alterations in semiconductors.

Spontaneous photon emission occurs due to quantum-mechanical instability.

Calculated emission rates and spectra are experimentally testable.

Abstract

Semiconductor's energy band and its degeneracy are altered when an external magnetic field varies, analogously to the appearance of Landau levels. Such alternation leads to the variation of energy levels and thus quantum-mechanical instability. As a consequence, spontaneous photon emission and/or paramagnetically screening effect take place. By computing total energy variation, we discuss why these effects are bound to occur. In addition, we calculate the rate and spectrum of spontaneous photon emission, which can be experimentally tested.
