Enhanced Continuous-wave Trahertz emission by nano-electrodes in a photoconductive photomixer
Semiconductor materials used as PCA-based photomixers must exhibit high resistivity, high carrier mobility and ultrashort carrier lifetime. Low-temperature-grown GaAs (LT GaAs) has been shown to have such characteristics 14–18 . The samples used in our experiment had [...]
Silicon carbide epitaxial wafer is a kind of silicon carbide wafer on which a single crystal film (epitaxial layer) with certain requirements and the same crystal as the substrate is grown on the silicon carbide substrate. In practical applications, almost all wide band gap [...]

Banknotes, documents, branded products, and sensitive goods like pharmaceuticals or technical components are often marked to distinguish them from imitations. However, some counterfeiters have learned to copy conventional fluorescent tags. In the journal Angewandte Chemie, Chinese scientists have now introduced a new, exceptional anti-counterfeit ink [...]

New InGaAs Structure Wafer
Indium gallium arsenide (InGaAs), also called gallium indium arsenide, is a common name for a family of chemical compounds of three chemical elements, indium, gallium, and arsenic. Indium and gallium are both boron group elements, often called “group III”, while arsenic is a [...]
