The transistor laser, invented by scientists at the University of Illinois at Urbana-Champaign, has been full of surprises. Researchers recently coaxed the device to reveal fundamental properties of ...

The drift-diffusion equations relevant for application to current flow in the double gate transistor are addressed. In standard operation this device has both source and drain heavily doped with the ...

To improve load capacity and transmission characteristics of crossed-axis helical gear drive, a generation approach of the gear pair with small-angle based on the curve contact element is proposed.
