Evidence of Silicon Band-Edge Emission Enhancement When Interfaced with SiO${}_2$:Er Films

S. Abedrabbo, A. T. Fiory, N. M. Ravindra

Nearly two-orders of magnitude increase in room-temperature band-to-band (1.067 eV) infrared emission from crystalline silicon, coated with erbium-doped sol-gel films, have been ac…
