Remarkably, both modulation schemes can be realized with just 1 and 2 all-graphene transistors, respectively, representing a drastic reduction in circuit complexity when compared with conventional ...

The devices are based on an AlAs/GaAs coupled quantum well structure and include the exciton optoelectronic transistor (EXOT), the excitonic bridge modulator (EXBM), and the excitonic pinch-off ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

Read Part 1 and Part 2 of this series. This article on FETs for voltage controlled circuits will cover FET modulator circuits and variable gain amplifier ...

The scalable method to create self-healing stretchable transistors and circuits introduced by the researchers could support the development of implantable devices that can measure ...

In this context, thermal transistors—capable of regulating heat transport in response to electrical stimuli—are poised to play a pivotal role in the next generation of devices.

Exotic 2-D materials hold great promise for creating atom-thin circuits that could power flexible electronics, optoelectronics, and other next-generation devices.

By this time transmitter design had advanced to more efficient Pulse-Width Modulation systems and ultimately FET all-transistor transmitters. The Vanguard, as its name suggests, was in the forefront ...

Optical Circuits: Single Photon Flips Transistor Switch Photons emerge as competitors to electrons in new computer circuits By Devin Powell & Nature magazine ...

A gadget that boosts a laser signal by a factor of 60 - based on the transfer of photons rather than electrons - could seed a new generation of ultrafast components for optical circuits. Junji ...
