We put forward another form of the non-planar ring lasers, in which the coer cube prism is the key element and the Nd:YAG crystal is used as a Porro prism to en
The water maser emission from the unusual supergiant, VY CMa, has been observed with the Urumqi 25m radio telescope. A simple redshifted maser spectrum was dete
The performance and characteristics of a cathodic arc plasma source, consisting of a titanium cathode, an anode with and without a tungsten mesh, and a coil pro
Electronic properties are investigated for three alumina polymorphs (corundum, Rb2 O3 (Ⅱ) and Pbnm perovskite),which are predicted as the stable structures und
A theoretical analysis is given for a higher order channel drop tunneling structure composed of two horizontal channels and a resonator system with two vertical
Device quality InAsP/InGaAsP strained multiquantum-well (MQW) structures are successfully grown by using gas source molecular beam epitaxy method. The grown MQW
ZnS and Zn(OH)2 capped ZnS semiconductor quantum dots (QDs) have been synthesized by the colloidal chemicalmethod using inorganic reagents. Transmission electro
