TI - Efficient electroluminescence from rare earth doped MOS diodes JO - Materials science and engineering / B VL - 81 SN - 0921-5107 CY - New York, NY [u.a.] PB - Elsevier M1 - PreJuSER-40432 SP - 102 - 104 PY - 2001 N1 - Record converted from VDB: 12.11.2012 AB - Efficient infra-red and visible electroluminescence (EL) has been obtained from implanted rare earth ions in the SiO2 of a silicon-metal-oxide-semiconductor (MOS) diode structure at room temperature. The rare earth ions are excited by the direct impact of hot electrons tunneling through the oxide at electric fields larger than 6 MV cm(-1). The internal quantum efficiencies of Er and Tb implanted MOS diodes are estimated at 10 and 3%, respectively. The high quantum efficiency is due to the high impact excitation cross-section > 10(-15) cm(-2). These observations on MOS structures are an experimental pl oof for efficient light generation by hot electron impact. (C) 2001 Elsevier Science B.V. All rights reserved.
