Quantum detector tomography of a time-multiplexed superconducting nanowire single-photon detector at telecom wavelengths [PDF]
Superconducting nanowire single-photon detectors (SNSPDs) are widely used in telecom wavelength optical quantum information science applications. Quantum detector tomography allows the positive-operator-valued measure (POVM) of a single-photon detector ...

Current Collapse-Free and Self-Heating Performances in Normally Off GaN Nanowire GAA-MOSFETs
Normally off lateral GaN nanowire gate-all-around MOSFETs have been fabricated on the GaN-on-insulator substrate. The dynamic measurement proved that the devices with various nanowire heights exhibit current collapse-free characteristics implying that ...
