When operating temperature 130K, tungsten just need 27nW Nano laser pumping energy. The researchers believe that due to the small size and low power consumption, tungsten photonic integrated circuits based nano lasers become a good substitute.

Researchers at Washington University and Stanford University have developed the device, the key is that they add a layer of tungsten photonic crystal selenium film on the chamber of the device. The study, published in Nature (doi: 10.1038 / nature14290). University of Washington doctoral student Wu Sanfeng introduction: "This is a recent discovery of this new type of semiconductor is very thin, and can be very efficient light-emitting researchers based on this material. characteristics, being produced transistors, light emitting diodes and solar cells, as well as tungsten Nano laser. "Meanwhile, researchers using another atomic sheet as the laser gain medium, can achieve a variety of purposes, for more convenient control of the laser to provide the conditions.

University of Washington professor Arka Majumdar introduction: "When using other materials, the gain medium is embedded, it is impossible to change our nano laser, you can remove or add such a monolayer structure, very convenient.."

Tungsten diselenide layer structure can be a direct bandgap exciton specifically limited in the scope of the luminal surface of 1nm. This material can also be achieved through a flexible external control laser operation, such as electrostatic gating and conduction current injection.

Ultra-thin semiconductor film laid photon cavity surface

The study was funded by the Air Force Office of Scientific Research, Office of Naval Research, the National Science Foundation, the US Department of Energy, the European Commission and the Washington Institute for clean energy.

Tungsten market: Despite the recent tungsten market weakness, no significant improvement in market demand, weak downstream demand continues, watching the market atmosphere. But tungsten prices have gradually dropped to the point where the cost line challenge, powder, APT smelter difficulties walking home goods, tentative offer continuous decline, the market is expected in mid-April tungsten or weak consolidation based.

Molybdenum market: International Molybdenum market continues downward, bottoming domestic tour continues, molybdenum concentrate inventory pressure, but supply and demand fundamentals can hardly be optimistic. Ferromolybdenum market inquiry reduced sales companies face a dilemma. Weak short-term market is expected to maintain stability.

To adapt to the new situation, the new normal economic development, changing the traditional business model, the morning of April 14, Dayu County organization prefecture mining enterprises, tungsten and non-ferrous metal processing enterprises and trade enterprises, nearly 30 enterprises attended by Tianjin International Exchange and mining rights Sinotrans Air Transportation Development Co., Ltd. Jiangxi Branch jointly undertaken by trade electricity supplier tungsten spot trading demo launches, demonstrations held in the county Xinsheng tungsten plant. Seminar hosted by the Entrepreneurs Association chairman Cao Liying Yu County, the county Board of Public Works letter sent to participate in the meeting.

County Clerk Caoai Zhen attended and delivered a warm speech. Marketing Manager of Tianjin International Exchange Lilley details of mining rights trading patterns and characteristics of electronic trading systems, and a live demonstration of the trading platform of the tungsten trade electricity supplier cash transaction process. End of the presentation, exchanges and Sinotrans Air Transportation Development Corporation staff for participating entrepreneurs live Q & A, conduct electricity provider communication on trade related matters tungsten spot trading.

With electricity supplier platform to carry out online transactions are currently many companies innovative business model to achieve the transformation and upgrading of important ways. The tungsten trade electricity suppliers trading demo promotion held for the county tungsten enterprises indicates a new development of business ideas, guide enterprises to expand marketing channels and sales path, create a broader market space, on the crack trade transactions tungsten barriers resolve tungsten county enterprise development problems, to help achieve the transformation and upgrading has far-reaching significance for the county tungsten and non-ferrous metal processing base trading platform has a great role in the promotion.
