Utilization of the high spatial-frequency component in adaptive beam shaping by using a virtual diagonal phase grating... In this experiment, a new and simple scheme of the adaptive beam shaping system to generate a square flattop shape with high uniformity and edge steepness using virtual diagonal phase grating encoded on a spatial-light modulator and a 4f system is proposed....
A new deep x-ray lithography beamline at delta... The generated structures are investigated afterchemical development concerning edge steepness, structure fidelity, and sidewall roughness
Estimation of carrier life time from intrinsic photoluminescence of zno... Hence, vigorous research activities on ZnO thin films, epilayers, and crystals took placeduring the last two decades, encompassing a vast variety of effects and phenomena such as birefringence,photocurrent, PL including sub-band gap emission, reflectance, transmittance, excitonic properties,Raman modes, and absorption edge steepness [1-4]....
Photon scanning tunneling microscope in combination with a force microscope... Images of an optical thin film (indium tin oxide) and a Langmuir-Blodgett layer (pentacosa diynoic acid) show absorption contrast with a lateral resolution of about 30 nm (based on edge steepness), which is well below the diffraction limi
