We report efficient quantum dot light-emitting diodes (QLEDs) using sizable 13-nm green-emission quantum dots as the emissive layer and solution-processable MoOx as the hole injection layer (HIL). The MoOx HIL was prepared by the decomposition of a solution of ammonium molybdate tetrahydrate at 80 °C under ambient conditions, further spin-coated onto an indium tin oxide substrate to facilitate hole...
Nanotwinned copper (nt-Cu) is drawing wide attention for it simultaneously demonstrates high strength and high ductility, which are thought to be mutually exclusive. According to previous studies, nanotwinned Cu may be the best structure for resisting electromigration damage. In this study, we deposit (111)-oriented nt-Cu using direct current with suitable additives on PCB substrates. Current density...
In present study, we prepared polypyrrole thin films by chemical oxidation polymerization method. The polypyrrole thin films were prepared with three different oxidants namely, ammonium per sulfate (APS), K2S2O8 and Fe(NO3)3. The deposited films were characterized by UV-Vis absorption spectroscopy, UV-Vis normal reflectance measurements, Scanning electron microscopy (SEM) and Cyclic Voltammetry. The...
A 1-V solution-processed polymer vertical transistor with on/off current ratio higher than 2 ?? 104 is firstly demonstrated. The channel length is 200 nm. A new structure is used to perform reliable leakage control. Significant impacts of thin film morphology and metal doping effect on the leakage current of organic vertical transistors are firstly observed and recognized as two new leakage phenomena...
In this study, the polymer/ceramic composites with high dielectric constant (HK=20 substrate) were prepared to investigate the temperature effects on electrical properties. The material properties of HK substrate were compared with those of FR4 substrate and MLCC-NPO capacitor device. Curie temperature of the HK substrate could be obtained from the curves of current densities varied with temperatures...
Fabrication of solar cells on cheap plastics, due to its demand for a low temperature processing (~100?C) needs adaptation of the cell structure of the state-of-the-art high efficiency thin film silicon solar cells made at high temperature (200?C). Use of a double n-layer (n-?c-Si/n-a-Si) instead of a single n-?c-Si layer improves Voc from a low 0.66 V to 0.82 V in the as deposited state of an n-i-p...
The multilayer films of LiCoO2/M/LiCoO2/M/LiCoO2 structure were prepared by a magnetron sputtering without post-annealing. The as-deposited multilayer films exhibited a nanocrystalline structure, which is similar to that of LiCo2 single layer films. Electrochemical performances of the LiCoO2/M multilayer films and a LiCoO2 single layer film were investigated at a current density ranging from 30 to...
