Over the last few decades, quantum chemistry has progressed through the development of computational methods based on modern digital computers. However, these methods can hardly fulfill the exponentia...
Optical transistor in silicon is a first(图)     Optical transistor  silicon       font style='font-size:12px;'> 2010/11/30
Researchers claim to have fabricated the first all-optical transistor on a silicon chip. This device allows the transmission of light emitted by one laser to be governed by the intensity of another. T...
Recently it has been experimentally shown that a graphene nanoribbon (GNR) can be obtained by unzipping a carbon nanotube (CNT). This makes it possible to fabricate all-carbon heterostructures that ...
SiGe islands are used to induce tensile strain in the Si channel of Field E ect Transistors to achieve larger transconductance and higher current driveabilities. We report on x-ray di raction experime...
Graphene transistor breaks new record(图)     Graphene transistor  new record       font style='font-size:12px;'> 2010/2/23
Physicists in the US have made the fastest graphene transistor ever, with a cut-off frequency of 100 GHz. The device can be further miniaturized and optimized so that it could soon outperform conventi...
Organic transistor mimics brain synapse(图)     Organic transistor  brain synapse       font style='font-size:12px;'> 2010/1/29
Researchers in France claim to have made the first transistor that mimics connections in the human brain. The device, which is based on pentacene and gold nanoparticles, could lead to a new generation...
The enhanced low-dose-rate sensitivity (ELDRS) and dose-rate dependence of vertical NPN transistors are investigated in this article. The results show that the vertical NPN transistors exhibit more de...
