Thermal activation of low-density Ga implanted in Ge
Natalie D. Foster, Andrew J. Miller, Troy A. Hutchins-Delgado +4
The nuclear spins of low-density implanted Ga atoms in Ge are interesting candidates for solid state-based qubits. To date, activation studies of implanted Ga in Ge have focused on…
Fabrication of quantum dots in undoped Si/SiGe heterostructures using a single metal-gate layer
T. M. Lu, J. K. Gamble, R. P. Muller +9
Enhancement-mode Si/SiGe electron quantum dots have been pursued extensively by many groups for \revEdit{their} potential in quantum computing. Most of the reported dot designs uti…
Rectified diode response of a multimode quantum cascade laser integrated terahertz transceiver
Gregory C. Dyer, Christopher D. Nordquist, Michael J. Cich +4
We characterized the DC transport response of a diode embedded in a THz quantum cascade laser as the laser current was changed. The overall response is described by parallel contri…
Position and mode dependent coupling of terahertz quantum cascade laser fields to an integrated diode
Gregory C. Dyer, Christopher D. Nordquist, Michael J. Cich +5
A Schottky diode integrated into a terahertz quantum cascade laser waveguide couples directly to the internal laser fields. In a multimode laser, the diode response is correlated w…
Interaction between Metamaterial Resonators and Inter-subband transitions in Semiconductor Quantum Wells
Alon Gabbay, John Reno, Joel R. Wendt +5
We report on the coupling and interaction between the fundamental resonances of planar metamaterials (split ring resonators) and inter-subband transitions in GaAs/AlGaAs quantum we…
Exceeding the Manley-Rowe quantum efficiency limit in an optically pumped THz amplifier
Ines Waldmueller, Michael C. Wanke, Weng W. Chow
Using a microscopic theory based on the Maxwell-semiconductor Bloch equations, we investigate the possibility of an optically-assisted electrically-driven THz quantum cascade laser…
