Journal ArticleDOI
Tuneable electromechanical comb generation
TL;DR: In this paper, a comb is created within the bandwidth of the fundamental mode of an electromechanical resonator using two continuous-wave pump excitations that piezoelectrically modulate the tension in the mechanical element and is seeded by a CW harmonic excitation of the signal.
Journal ArticleDOI
Dynamical coupling between a nuclear spin ensemble and electromechanical phonons
Yuma Okazaki,Yuma Okazaki,Imran Mahboob,Koji Onomitsu,Satoshi Sasaki,Shuji Nakamura,Nobu-Hisa Kaneko,Hiroshi Yamaguchi +7 more
TL;DR: The authors show that they can shift the NMR frequency and drive the nuclear spins into the resolved-sideband regime by using the tunable phonon states from an electromechanical resonator.
Journal ArticleDOI
On-Chip Coherent Transduction between Magnons and Acoustic Phonons in Cavity Magnomechanics
TL;DR: In this paper , a planar cavity magnomechanical system was proposed to implement magnon-phonon coupling at room temperature, where the cavity of surface acoustic waves enhances the spatial and spectral power density.
Journal ArticleDOI
Influence of surface reconstruction on the As desorption process from a (001) GaAs surface evaluated by improved high-energy electron-reflectivity measurements.
TL;DR: Electron-beam specular reflectivity in high-energy electron diffraction is evaluated quantitatively by measuring the reflected electron-beam current and as desorption from a (001) GaAs surface is studied in detail.
Journal ArticleDOI
Evaluation of the highly coherent surface structure of the GaAs (411)A plane using scanning tunneling microscopy
TL;DR: In this paper, the surface structure of (411)A GaAs was observed by atomically resolved scanning tunneling microscopy for the first time and a highly ordered structure of straight atomic rows stretching along the [1 1 ] direction was observed.
