We demonstrate a GaN quantum dot ultraviolet light-emitting diode that uses tunnel injection of carriers through AlN barriers into the active region. The quantum dot heterostructure is grown by molecular beam epitaxy on AlN templates. The large lattice mismatch between GaN and AlN favors the formation of GaN quantum dots in the Stranski-Krastanov growth mode. Carrier injection by tunneling can ...

W e would like to congratulate Dr Frank Noyes for the publication of his article “The Function of the Human Anterior Cruciate Ligament and Analysis of Singleand Double-Bundle Graft Reconstructions” in the first issue of Sports Health (volume 1, issue 1, pp 66-75). In the article, Dr Noyes pointed out that the typical “tibial PL [posterolateral] to femoral AM [anteromedial]” tunnel placement is ...

background: hereditary non-polyposis colorectal cancer (hnpcc) is a common hereditary cancer predisposing syndrome has molecular and clinicopathological features still have remained ambiguous within iranian populations. we discuss in this article some molecular and clinicopathological features of the condition. methods: the study was a descriptive retrospective and designed on 1659 colorectal c...

While the effects of lattice mismatch-induced strain, mechanical strain, as well as the intrinsic strain of thin films are sometimes detrimental, resulting in mechanical deformation and failure, strain can also be usefully harnessed for applications such as data storage, transistors, solar cells, and strain gauges, among other things. Here, we demonstrate that quantum transport across magnetic ...

Nowadays deep excavations are needed for construction of foundation of high rise buildings, providing space for parking and etc. In some cases deep excavations may be constructed in the vicinity of the subway tunnels and causes unpredicted extra displacements and internal forces in tunnel lining of tunnels which were not designed for them and consequently affect serviceability of tunnel. Theref...

2014 Impedance properties of a waveguide TM-mode near cut-off are demonstrated to improve Josephson junction coupling to the waveguide. Revue Phys. Appl. 20 (1985) 215-217 MARS 1985, PAGE Classification Physics Abstracts 74.50 4l.lOH It is generally recognized that the experimentally observed weak coupling of a Josephson tunnel junction to the external world is caused by the considerable impeda...

PURPOSE To assess the length of the patellar tendon in Chinese and its correlation with patient age, gender, and operated side. METHODS 109 men and 11 women aged 15 to 45 (mean, 25) years underwent arthroscopic bone-tendon-bone reconstruction for anterior cruciate ligament (ACL) insufficiency. 55 (46%) injured the left side, and 65 (54%) the right side. Each patient's age, gender, and operate...
