Tantalum etched by H 2 O 2 solution shows best performance to be the source/drain electrodes of inverted staggered amorphous Indium Gallium Zinc Oxide thin film transistors among the investigated five metal materials. In addition, the etching property is improved significantly by adding aqueous ammonia properly. 1. Introduction Amorphous oxide semiconductor(More)
The gate bias and temperature instability of InGaZnO TFTs were improved by adopting double stacked channel layer (DSCL). The mechanism of V th shift under stress was studied by this structure. An interface with of less oxygen plasma damaging and lower oxygen vacancies in bulk were achieved by DSCL, resulting in a higher stability of V th. 1. Introduction(More)
The ordering degree of nanostructures is the key to determining the uniformity of surface-enhanced Raman scattering (SERS). However, fabrication of large-area ordered nanostructures remains a challenge, especially with the ultrahigh-density (>10(10) cm(-2)). Here, we report a fabrication of large-area ultrahigh-density ordered Ag@Al2O3/Ag core-shell(More)
In situ characterization of the work function of quasi one dimensional nanomaterials is essential for exploring their applications. Here we proposed to use the electrostatic deflection induced by work function difference between nanoprobe and nanowire for in situ measuring the local work function along a free standing nanowire. The physical mechanism for(More)
The epitaxial growth of carbon nanotubes (CNTs) is an important subject of research. Recent attention has been paid to finding new strategies for the controlled growth of single-wall CNTs with a defined chirality. In addition, many potential applications require multiwall CNTs (MWCNTs) to grow vertically from the substrate and the interface property is(More)
This study investigates intraseasonal oscillations (ISOs) of upper tropospheric water vapor (UTWV) in the Asian monsoon region in boreal summer by using data with high spatial and temporal resolution from the AIRS instrument. There are robust intrasea-sonal cycles with periods of 30–60 days and 10–20 days in the UTWV field over both 5 South Asia and East(More)
One of the most fascinating and important merits of graphene plasmonics is their tunability over a wide range. While chemical doping has proven to be a facile and effective way to create graphene plasmons, most of the previous studies focused on the macroscopic behaviors of the plasmons in chemically-doped graphene and little was known about their nanoscale(More)
Due to their optical magnetic and electric resonances associated with the high refractive index, dielectric silicon nanoparticles have been explored as novel nanocavities that are excellent candidates for enhancing various light-matter interactions at the nanoscale. Here, from both of theoretical and experimental aspects, we explored resonance coupling(More)
