Improved graphene-base heterojunction transistor with different collector semiconductors for high-frequency applications


New research paper from TU Dresden & others. Abstract "A new kind of transistor device with a graphene monolayer embedded between two n-typesilicon layers is fabricated and characterized. The device is called graphene-base heterojunction transistor (GBHT). The base-voltage controls the current of the device flowing from the emitter via graphene to the collector. The transit time for e... » read more

Bigger, Brighter TVs


The flat panel display (FPD) industry is undergoing a renaissance, with suppliers rolling out a dizzying array of new, high-resolution technologies for mobile devices, computers and TVs. But despite being in the eye of the innovation storm, FPD equipment makers remain cautious—and for good reason. There are a slew of new LCD fabs being built today, mostly in China. This, in turn, is promp... » read more
