Dispersive mode coupling is a promising mechanism for the development of advanced micro/nanoelectromechanical devices. However, strong coupling strength remains a key challenge lim…
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…
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…
