The development of molecular machines has long been a dream of scientists and is expected to revolutionize many aspects of technology and medicine. As the prerequisite of a practicable molecular ...

A theoretical analysis is presented of a solid-state power amplifier consisting of a unidirectional transmission line loaded by a series of negative-resistance diodes. Numerical calculations of the ...

Molecules have limited mobility in the solid state because of the strong intermolecular interactions, and therefore, applications based on solid-state molecular motions are seldom explored. Herein, by ...

We present an overview of solid-state integrated circuit amplifiers approaching terahertz frequencies based on the latest device technologies which have emerged in the past several years. Highlights ...
