Control of heat flow is crucial for thermal logic devices and thermal management, with theoretical exploration preceding limited experimental progress in actively controlling heat flow. The device ...

Gallium nitride (GaN) is an ideal material for applications requiring high switching speeds and minimal power losses. While the wide-bandgap material can certainly improve a system’s overall ...

Researchers have built working transistors from graphene nanoribbons less than a nanometer wide, achieving room-temperature ...

CAMBRIDGE, MA – Silicon transistors, which are used to amplify and switch signals, are a critical component in most electronic devices, from smartphones to automobiles. But silicon semiconductor ...

Switching has almost always meant “hard" switching, which is simple but comes with all kinds of electrical and thermal stresses. Soft switching employs more sophisticated design to reduce stresses and ...

Probably the most important invention of the 2oth Century was the transistor. The first point contact transistor shown below was made at Bell Laboratories. The workbench of John Bardeen and Walter ...
