Ambipolar two-dimensional semiconductors exhibit electrostatically modulable carrier polarity, enabling reconfigurable electronic functionalities critical for the development of logic-in-memory computing architectures. However, ambipolar conduction is generally weak and unbalanced, in particular, under ambient operating conditions. Here, we develop a universal nonvolatile device architecture based on tungsten diselenide (WSe2) delicately enhance its transport via scanning probe lithography,...
The mechanical and mechanochemical synergistic micro-grinding technology was proposed for grinding hard brittle materials, especially fused silica micro parts in this work. Compounded abrasive tools with diamond abrasives on the outer layer cerium oxide inner were designed fabricated. Efficient initially achieved by processing of super abrasives, then ultra-precision obtained process to remove surface or subsurface damage. This study firstly analyzed contact model single particle...
Metal‐assisted chemical etching (MACE) is a cost‐effective method to fabricate Si nanostructures including silicon nanowires (SiNWs) and nanoholes (SiNHs). However, the preparation of metallic template for MACE would require complex experimental conditions strict cleaning process multiple steps. Herein, superlens‐enhanced laser interference lithography applied directly complicated patterns then used obtain hybrid SiNW SiNH arrays. Ag films are first deposited on substrates, 1064 nm high...
A one-step lithography method based on a superlens is proposed to fabricate diffraction-unlimited metallic patterns. By controlling the material parameters and distribution of impinging energy, various phenomena, such as periodic nanonetworks, ultrathin nanowires (sub-50-nm feature size), variable-sized nanoparticles (ranging from sub-10 nm several hundreds nanometers), are fabricated using 1,064-nm nanosecond laser. The evolution pathway phenomena explained by dewetting process films....
Ultrathin broadband absorber maintaining a near-uniform low reflectivity over wavelength is essential for many optical applications, such as light harvesting and nanoscale imaging. Recently, there has been considerable interest in employing arrays of high-index dielectric Mie resonators on surfaces to trap reduce the reflectivity. For Mie-resonant metasurfaces, however, antireflection properties featuring both flat reflectance curve wide bandwidth are hard be satisfied simultaneously, an...
Minimizing undesired reflection is important for solar cell applications. Recently, high-index dielectric Mie resonator has attracted significant attention due to its efficient light trapping and antireflection performance. However, such Mie-resonant ultrathin coating, properties presenting both a uniform low-valued reflectance curve large bandwidth are difficult be satisfied simultaneously. Here, we demonstrate strategy achieve broadband using quasi-random resonators. Different shapes of...
