Metal halide perovskites have become well-deserved “star” materials among a variety of semiconductors owing to their excellent optoelectronics properties, such as high photoluminescence (PL) quantum ...
Physicists are learning to carve laser beams into intricate shapes that can grab hold of electrons and push them with a ...
(a) Schematic of the laser direct-writing system. (b) Vertical view of the cantilever of the SNOM tip. (c) Details of the pyramid tip structure and three-dimensional (3D) multiphysics model in the ...
Meanwhile, DLW, based on the interaction between light and matter, is an efficient, contactless, mask free, and depth-resolved micro-patterning technique. It is typically performed by coupling a laser ...
