In nanoimprint lithography (NIL), it is essential to provide stamps with good anti-sticking surface properties. A low surface energy release layer on the stamps helps to improve the imprint quality, and it also increases the stamp lifetime significantly by preventing surface contamination. Low adhesion and friction at structure sidewalls can only be assured if the stamp is fully covered with a ...

It is shown that coating graphene-silicon (Gr/Si) Schottky junction based solar cells with graphene oxide (GO) improves the power conversion efficiency (PCE) of the cells, while demonstrating unprecedented device stability. The PCE has been shown to be increased to 10.6% (at incident radiation of 100 mW cm(-2)) for the Gr/Si solar cell with an optimal GO coating thickness compared to 3.6% for a...

The stoichiometry and hydrogen content of hot-wire (HW)-grown silicon nitride was examined as a function of SiH yNH 4 3 flow ratio. The effect of post-deposition hydrogenation treatment on overall film hydrogen content was determined. The hydrogen release properties in Si-rich and N-rich nitride layers were characterized by annealing treatments. Defect hydrogenation was studied using Fourier tr...

In this contribution, we present an electron selective passivating contact metallised with a low temperature process to target front side applications in crystalline silicon (c-Si) solar cells. addition interfacial oxide (SiOx) and in-situ phosphorous doped micro-crystalline (?c-Si(n)) layer, it comprises ultra-thin indium tin (ITO) layer of 15 nm for lateral conductivity hydrogen rich nitride ...

Abstract VO2 films are widely considered as one of the most suitable material to act smart windows. Although this system is able function, durability film has been an issue surface may oxidize by converting V4+ V5+. To overcome problem, attempt made coat with ZnO, which can assist creating a resistance layer prevent further oxidation VO2. Here, VO2/ZnO bilayer was prepared facile method compris...

Thermodynamical fluctuations impose random noise on the position of optical components. It is predicted that this thermal noise will limit the sensitivity of interferometric gravitational-wave detectors in their most sensitive frequency band. Thermal noise originating from optical coatings was first considered in the context of interferometric gravitational wave detectors. Its true significance...

This study aimed to detect the expression of Slit signaling protein ligand Robo protein in human bladder cancer and para-carcinoma tissue, and observe the tumor cell survival and growth by inoculating the bladder cancer cells with the blocked signaling protein into the subcutaneous tissue of nude mice. The expression of Robo protein was detected in T24 cells in human bladder uroepithelium carci...
