Abstract
Summary form only given. The demonstration of a Si1-xGe x/Si multiquantum-well infrared detector is reported. The quantum-well structure consists of 50 periods of 30-Å-thick Si0.85Ge0.15 wells (doped p=1×1019 cm-3) separated by 300-Å-thick undoped Si barriers with p+ ohmic contacts on both sides. The quantum well is designed so that only the ground state is confined in the quantum well. The feasibility of Si-based highly sensitive long-wavelength infrared detectors with the advantage of monolithic integration with Si integrated circuits was demonstrated
