We propose and evaluate vertical hot-electron terahertz (THz) detectors based on black-As1−xPx/graphene/black-As1−yPy (b-AsP/G/b-AsP) heterostructures. The operation of these detectors is as ... Read More

Charge carriers in graphene, i.e., massless Dirac fermions, form a unique sequence of Landau levels at high magnetic fields, and the cyclotron resonance in graphene is distinctly different from t ... Read More

We propose a method for fabricating high-performance epitaxial graphene field-effect transistors (EG-FETs), involving a microwave-annealing-treated solution-based Al2O3 (MWA-treated sol-Al2O3) la ... Read More

The 2D crystal of sp2-bonded carbon atoms (graphene) is suitable for high-speed device applications owing to its excellent electronic properties and ultrathinness that suppresses the so-called sh ... Read More

We demonstrated a simple technique for monitoring distance variation with millimeter precision between two remote sites using off-the-shelf wireless communication modules. The need for the flexi ... Read More

Field-effect transistors (FETs) are considered promising devices for future development owing to their application in large-area electronics. In this research, we focus on the fabrication and op ... Read More
