Coherent interaction of a-few-electron quantum dot with a terahertz optical resonator
Kazuyuki Kuroyama, Jinkwan Kwoen, Yasuhiko Arakawa +1
We have investigated light-matter hybrid excitations in a quantum dot (QD)-terahertz (THz) optical resonator coupled system. We fabricate a gate-defined QD in the vicinity of a THz…
Thermal conductivity minimum of graded superlattices due to phonon localization
Yangyu Guo, Marc Bescond, Zhongwei Zhang +4
The Anderson localization of thermal phonons has been shown only in few nano-structures with strong random disorder by the exponential decay of transmission to zero and a thermal c…
Giant enhancement in the thermal responsivity of microelectromechanical resonators by internal mode coupling
Ya Zhang, Ryoka Kondo, Boqi Qiu +2
We report on a giant enhancement in the thermal responsivity of the doubly-clamped GaAs microelectromechanical (MEMS) beam resonators by using the internal mode coupling effect. Th…
Controllable pn junctions in threedimensional Dirac semimetal CdAs nanowires
Janice Ruth Bayogan, Kidong Park, Zhuo Bin Siu +11
We demonstrate a controllable pn junction in a threedimensional Dirac semimetal (DSM) CdAs nanowire with two recessed bottom gates. The device exhibits four different…
Enhanced thermal sensitivity of MEMS bolometers integrated with two-dimensional phononic crystals
Ya Zhang, Boqi Qiu, Naomi Nagai +3
We have fabricated two-dimensional phononic crystal (PnC) structures on GaAs doubly-clamped microelectromechanical system (MEMS) beam resonators to modulate their thermal propertie…
Rattling motion of a single atom in a fullerene cage molecule sensed by terahertz spectroscopy
Shaoqing Du, Ya Zhang, Kenji Yoshida +1
Upon the discovery of the superatom states in endohedral metallofullerenes (EMFs), the superatom properties have become attractive, because ultrafast motion of the trapped atom mod…
