A circulator is a waveguide device that allows energy to travel in one direction only. The tunnel diode in the figure shown is connected across a tuned-input circuit. This arrangement normally ...

Fairview Microwave Inc. recently released a full line of coaxial-packaged tunnel diode detectors that are are well-suited for proof-of-concept and prototype applications. Such application areas ...

Sean L. Rommel (IEEE Senior Member) received the B.S. and Ph.D. degrees in Electrical Engineering from the University of Delaware. His Ph.D. work focused on the realization of a CMOS compatible ...

Australian semiconductor developer BluGlass has successfully demonstrated working tunnel junction laser diodes in a world-first proof-of-concept using its proprietary remote plasma chemical vapour ...

(Nanowerk News) Simulation of devices at atomistic scale is today very important as, in the last years, semiconductor devices dimensions are approaching typical lengths of a few nanometers. Those ...

The illustration (left) shows the different layers of the double-barrier structure; the two GeSiSn barriers are stacked between layers of GeSn. The table (right) indicates the layers where hydrogen ...

Resonant tunnelling diodes (RTDs) in Gallium Nitride (GaN) heterostructures constitute a frontier in quantum device engineering, where quantum mechanical tunnelling and precise interface control ...
