Latest Patents
Hector M Del Castillo holds a patent for "Long-wavelength PTSI infrared detectors and method of fabrication thereof." This patent demonstrates extended cutoff wavelengths of PtSi Schottky infrared detectors in the long wavelength infrared (LWIR) regime for the first time. The innovation was achieved by incorporating a 1-nm-thick p+ doping spike at the PtSi/Si interface. The extended cutoff wavelengths resulted from the combined effects of an increased electric field near the silicide/Si interface due to the p+ doping spike and the Schottky image force. The p+ doping spikes were grown by molecular beam epitaxy at 450 degrees Celsius using elemental boron as the dopant source, with doping concentrations ranging from 1×1019 to 1×1021 cm-3. The cutoff wavelengths were shown to increase with increasing doping concentrations of the p+ spikes.
