Detection of incoherent broadband terahertz light using antenna-coupled high-electron-mobility field-effect transistors
Hua Qin, Xiang Li, Jiandong Sun +5
The sensitivity of direct terahertz detectors based on self-mixing of terahertz electromagnetic wave in field-effect transistors is being improved with noise-equivalent power close…
High-efficiency spontaneous terahertz emission from electrically-excited plasmons in AlGaN/GaN two-dimensional electron gas
Hua Qin, Yao Yu, Jiandong Sun +16
The advance of terahertz science and technology yet lays wait for the breakthrough in high-efficiency and high-power solid-state terahertz sources applicable at room temperature. P…
Probing and modelling the localized self-mixing in a GaN/AlGaN field-effect terahertz detector
J. D. Sun, H. Qin, R. A. Lewis +5
In a GaN/AlGaN field-effect terahertz detector, the directional photocurrent is mapped in the two-dimensional space of the gate voltage and the drain/source bias. It is found that…
Pauli spin blockade and lifetime-enhanced transport in a Si/SiGe double quantum dot
C. B. Simmons, Teck Seng Koh, Nakul Shaji +12
We analyze electron transport data through a Si/SiGe double quantum dot in terms of spin blockade and lifetime-enhanced transport (LET), which is transport through excited states t…
Single-electron quantum dot in Si/SiGe with integrated charge-sensing
C. B. Simmons, Madhu Thalakulam, Nakul Shaji +7
Single-electron occupation is an essential component to measurement and manipulation of spin in quantum dots, capabilities that are important for quantum information processing. Si…
Direct mechanical mixing in a nanoelectromechanical diode
Hyun S. Kim, Hua Qin, Robert H. Blick
We observe direct mechanical mixing in nanoelectromechanical transistors fabricated in semiconductor materials operating in the radio frequency band of 10-1000 MHz. The device is m…
