Lin, T.; Park, J. S.; Gunapala. S. D.; Jones, E. W.; del Castillo, H. M., 1993, "Tailorable Doping-Spike PtSi Infrared Detectors Fabricated by Si Molecular Beam Epitaxy", https://hdl.handle.net/2014/36017, ['1993 International Conference on Solid State Devices and Materials', 'Chiba, Japan', 'Japan Journal of Applied Physics'], JPL Open Repository
By incorporating a 1-nm-thick p+ doping spike at the PtSi/Si interface, we have successfullydemonstrated extended cutoff wavelengths of PtSi Schottky infrared detectors. The extended cutoffwavelengths resulted from the reduced effective potential barriers due to the combined effe... |
