Light-Emitting Porous Silicon in High Magnetic Fields
Published online by Cambridge University Press: 15 February 2011
Abstract
Photoluminescence from porous silicon was studied in a helium atmosphere and at high magnetic fields. In a magnetic field, the spectral peak had a negligible shift, amounting to +0.2 ±0.5 meV at B= 18T. If quantum confinement is the major effect, then the conduction electron would be confined to a diameter of less than 3.5 nm.
