We studied the effects of low-energy electron beam irradiation up to 10 keV on graphene-based field effect transistors. We fabricated metallic bilayer electrodes to contact mono- and bi-layer graphene flakes on SiO₂, obtaining specific contact resistivity ρ c ≈ 19 k Ω · µ m 2 and carrier mobility as high as 4000 cm²·V-1·s-1. By using a highly doped p-Si/SiO₂ substrate as the back gate, we analy...

A simple method for modifying a polymer surface to induce lipid bilayer formation by vesicle fusion is described. A silicate gel was prepared by condensation of tetraethyl orthosilicate (TEOS) in the presence of acid. When applied to a poly(methylmethacrylate) substrate, either a rough or a smooth layer could be produced, depending on the method used for the application. The smooth surface indu...

The simplest cell-like structure, the lipid bilayer vesicle, can respond to mechanical deformation by elastic membrane dilation/thinning and curvature changes. When a protein is inserted in the lipid bilayer, an energetic cost may arise because of hydrophobic mismatch between the protein and bilayer. Localized changes in bilayer thickness and curvature may compensate for this mismatch. The pept...

This paper investigates the development of a novel framework and its implementation for the nonlinear tuning of nano/microresonators. Using geometrically exact mechanical formulations, a nonlinear model is obtained that governs the transverse and longitudinal dynamics of multilayer microbeams, and also takes into account rotary inertia effects. The partial differential equations of motion are d...

Optical vortex, possessing an annular intensity profile and an orbital angular momentum (characterized by an integer termed a topological charge) associated with a helical wavefront, has attracted great attention for diverse applications due to its unique properties. In particular for terahertz (THz) frequency range, several approaches for THz vortex generation, including molded phase plates co...

We study how FeO wüstite films on Ru(0001) grow by oxygen-assisted molecular beam epitaxy at elevated temperatures (800–900 K). The nucleation and growth of FeO islands are observed in real time by low-energy electron microscopy (LEEM). When the growth is performed in an oxygen pressure of 10(−6) Torr, the islands are of bilayer thickness (Fe–O–Fe–O). In contrast, under a pressure of 10(−8) Tor...

Monolayer FeSe grown on ${\mathrm{SrTiO}}_{3}$ provides a playground for high-${T}_{c}$ superconductivity. Authors of recent study have shown the importance stripy instability superconductivity enhancement in FeSe/${\mathrm{SrTiO}}_{3}$. However, it is still under debate whether such stripe phase ubiquitously bound to interfacial Here, we report molecular beam epitaxy growth and low-temperature...
