Daniel Walkup, Fereshte Ghahari, Steven R. Blankenship, Kenji Watanabe, Takashi Taniguchi, Nikolai Zhitenev, Joseph A. Stroscio
Coupled quantum dots have been realized in a wide variety of physical systems and have attracted interest for many different applications. Here, we examine novel graphene quantum dots in backgated devices on hBN, and visualize their merger using scanning

Superconducting Nanowire Single-Photon Detector Arrays for the Near- to Mid-Infrared

October 31, 2023
Author(s)
Benedikt Hampel, Richard Mirin, Sae Woo Nam, Varun Verma
Superconducting Nanowire Single-Photon Detectors (SNSPDs) are excellent devices for the analysis of faint light from the ultraviolet to the mid-infrared. Recent developments push their broad wavelength bandwidth further into the mid-infrared towards 20 μm

Quantum Plexcitonic Sensing

October 11, 2023
Author(s)
Peng Zheng, Stephen Semancik, Ishan Barman
Quantum sensing is poised to deliver unparalleled performance compared to its classical counterpart. While fundamental to quantum sensing, quantum state control has been traditionally limited to extreme conditions, such as a high vacuum or an ultra-stable

Electrostatic modulation of thermoelectric transport properties of 2H-MoTe2
