Metamaterials made of nanoscale inclusions or artificial unit cells exhibit exotic optical properties that do not exist in natural materials. Promising applications, such as super-resolution imaging, cloaking, hyperbolic propagation, and ultrafast phase velocities have been demonstrated based on mostly micrometer-scale metamaterials few metamaterials. To date, most are created using costly tedious fabrication techniques with limited paths toward reliable large-scale fabrication. In this...

Thin-film resonators and scanning probe microscopies (SPM) are usually used on low-frequency mechanical systems at the nanoscale or larger. Generally, off-chip approaches applied to detect vibrations in these systems, but methods not much appropriate for atomic-thin-layer devices with ultrahigh characteristic frequencies ultrathin thickness. Primarily, those based atomic-layers provide highly improved properties, which inapproachable conventional nanoelectromechanical (NEMS). In this report,...
The fundamental logic states of 1 and 0 in Complementary Metal-Oxide-Semiconductor (CMOS) are essential for modern high-speed non-volatile solid-state memories. However, the accumulated storage signal conventional physical components often leads to data distortion after multiple write operations. This necessitates a write-verify operation ensure proper values within 0/1 threshold ranges. In this work, non-gradual switching memory with two distinct stable resistance levels is introduced,...
2D materials-based nanoelectromechanical resonant systems with high sensitivity can precisely trace quantities of ultra-small mass molecules and therefore are broadly applied in biological analysis, chemical sensing, physical detection. However, conventional optical capacitive transconductance schemes struggle to measure high-order mode effectively, which is the scientific key further achieving higher accuracy lower noise. In present study, different vibrations monolayer Ti
La 0.60 Sr 0.40 MnO 3 (LSMO) thin films of varying thickness from 12 to 55 nm were deposited using the pulsed-laser deposition technique onto single-crystalline SrTiO3 (STO) and STO-buffered Si substrates. The Tc LSMO grown on substrates decreases faster than directly STO with decreasing film thickness. LSMO/STO shows at about 360 K, which is close bulk value, whereas similar reduced 320 K. This difference attributed strain interfacial disorders in STO/Si. surface morphology influenced by...
