High-valent transition-metal (Ti or Mo)-doped ZnO thin-film transistors (TFTs) were fabricated using radio-frequency magnetron sputtering at 150$^{\circ}{\rm C}$ . When the Ti or Mo was doped in the ZnO channel, device characteristics, such as threshold voltage, were modulated and field effect mobility could be enhanced. The device stability of the TFTs with a low Mo content was dramatically improved,...
Land Use / Cover Change (LUCC) is an essential component in the field of regional environmental monitoring and economic development analysis. Its motivation is to get an in-depth understanding of dynamic process, leading causes and evolution mechanism of regional land use change, which provide accurate information for land administration to develop local economic development planning and management...
Aim to the actual needs of marine remote sensing in China, MRSMDVS (Marine Remote Sensing Multidimensional Dynamic Visualization System) is designed and developed to support assistant decision for reasonable exploitation of marine natural resource. This paper starts with the introduction of COM basic principle, presents characteristics of marine remote sensing data, sets up multidimensional dynamic...
A laser generation and optical difference detection method of surface acoustic waves is used for characterizing elastic constants of thin films deposited on substrates. The film/substrate samples are prepared by a RF magnetron sputtering technique. Teflon-like films, deposited on three kinds of substrates, silicone plates, glass and copper plates, have been studied and the related parameters have...
Dielectric characteristics of LDPE filled with micro- and nano-sized particles of SiO2 were studied in this paper. The dependence of the loss factor and dielectric constant of composites on frequency was investigated in a relatively wide frequency range, and the roles of the size and loading level of the filler are discussed. Compared with additive-free LDPE, incorporating nano-sized SiO2 can effectively...
