NbH2 hydride is an important material in hydrogen storage materials.However,until now there have been no experimental and theoretical data on the elastic and th
We investigate the electronic structures and magnetic properties of ZnO doped with N,Cu,and (Cu+N) by using a first principles method and considering the strong
A new type ofgermanate-tellurite glass with doped Tm3+ ions is synthesized and its 1.8 μm emission properties have been studied for its application as a laser
In literature,some experiments of the interaction of a singly ionized ion with clean metallic surfaces were related to electron and visible light emission.[1-4]
Enhanced multiwave mixing processes due to atomic coherence have been experimentally reported in several multilevel atomic systems.[1-3] The keys in such enhanc
