Journal ArticleDOI
Carbon Multiprobe on a Si Cantilever for Pseudo-Metal-Oxide-Semiconductor Field-Effect-Transistor
TL;DR: In this article, a scanning probe microscopy system with multiple probes has been applied to measurements of local electrical properties of semiconductor films, and the results clearly demonstrate that this multiprobe system can be a powerful and widely applicable tool for measuring local device characteristics.
Journal ArticleDOI
Microscopic Raman Mapping of Epitaxial Graphene on 4H-SiC(0001)
Ryong-Sok O,Atsushi Iwamoto,Yuki Nishi,Yuya Funase,Takahiro Yuasa,Takuro Tomita,Masao Nagase,Hiroki Hibino,Hiroshi Yamaguchi +8 more
TL;DR: In this article, a quality control method for wafer-scale epitaxial graphene grown on SiC substrates was proposed, where wave numbers of Raman peaks (G and 2D band peaks) were strongly correlated with the strain in the graphene film.
Journal ArticleDOI
Changes of Conductivity in Patients With Second- or Third-Degree Atrioventricular Block After Pacemaker Implantation
Masataka Sumiyoshi,Yasuro Nakata,Masayuki Yasuda,Takashi Tokano,Yasuhiko Ohno,Shunsuke Ogura,Yuji Nakazato,Hiroshi Yamaguchi +7 more
TL;DR: Most patients with complete AV block did not recover AV conductivity after the long-term follow-up, and second-degree BH and H-V block tended to progress to completeAV block.
Journal ArticleDOI
InAs/AlGaSb heterostructure displacement sensors for MEMS/NEMS applications
TL;DR: In this paper, a novel microelectromechanical displacement sensor with a surface InAs conductive layer of nanometer-scale thickness based on MBE-grown InAs/AlGaSb heterostructures was successfully fabricated.
Journal ArticleDOI
Virtual exceptional points in an electromechanical system
TL;DR: In this article, an optomechanical-like parametric modulation is employed to dynamically couple two different vibration modes and in the appropriate parameter regime their imaginary eigenvalues coalesce whilst their normal modes split.
