Newly engineered substrates consisting of semiconductor-on-insulator are gaining much attention as starting materials for the subsequent transfer of semiconductor nanomembranes via selective etching of the insulating layer. Germanium-on-insulator (GeOI) substrates are critically important because of the versatile applications of Ge nanomembranes (Ge NMs) toward [...]

Fundamental issues of device-relevant low temperature GaAs and related materials properties
In the past few years, a flurry of activity has been devoted to the studies and device applications of non-stoichiometric GaAs grown by molecular beam epitaxy at the extremely low temperature (LT) of 250 [...]
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 [...]
