Because of the monolayer thickness of graphene, improved SMS transistors with a semimetallic graphene-base electrode are now feasible for high-frequency applications. In this study we report about a device that consists of amorphous silicon, graphene, and crystalline silicon. For the first time, this device is fabricated by a four-mask lithography process which leads to significant improvements in the device performance. A strongly increased common-emitter current gain of 2\% could be achieved while the on-off ratio improved to 1.6 × 105, which is already higher than predicted theoretically. This could be mainly attributed to better interface characteristics and decreased lateral dimensions of the devices. A cutoff frequency of approximately 26 MHz could be forecasted based on the DC measurements of the device.}, language = {en} } @misc{SimonTaeschnerRiederetal., author = {Simon, Sylvio and Taeschner, Dirk and Rieder, Thomas and Schneider, Robert and Hernschier, Stephan and Magister, Jan and Fritsch, Tim and Abbasov, Ilgar and Turabov, Dashqin and Globa, Svetlana}, title = {Investigation in characteristics of belt conveyors and their idler rollers for coal-fired power plants}, series = {Safety and Reliability of Power Industry}, volume = {14}, journal = {Safety and Reliability of Power Industry}, number = {3}, issn = {2542-2057}, doi = {10.24223/1999-5555-2021-14-3-125-133}, pages = {125 -- 133}, abstract = {Belt conveyors are highly efficient systems used in mining and other industries to transport bulk materials, mainly brown coal and overburden, over distances ranging from short distances to several kilometres. For technical reasons, their operation is associated with noise emissions. During inspections and maintenance this can lead to increased noise exposure of employees. In the vicinity of residential buildings or in areas needing protection, exceeding the emission limits can lead to a temporary restriction of the operation of these high performance installations. Measures are required to reduce the noise impact primarily at the source or in the immediate vicinity. The acoustic and mechanical parameters are investigated on a test bench at the Technical University of Brandenburg (BTU) Cottbus-Senftenberg as part of the drive assembly tests in cooperation with LEAG. The stages of these tests are: Run-up test. In this test the supporting roller is accelerated under test load to a circumferential speed of 10 m/s and the sound pressure level is recorded. This makes it possible to calculate the sound emission as a function of the peripheral speed; Recording the geometry of the idler gear. An accurate description of the geometry of the idler housing allows conclusions to be drawn about the possible causes of excitation. The defined characteristics serve to quantify the acoustic effect of the driven rollers and derive specifications for use in belt conveyor systems. Based on the special requirements to the planned belt conveyor system, an adapted selection of low-noise idler rollers can be made at an early stage on the basis of specified parameters and confirmed test results.}, language = {en} }
