TL;DR: In this article, the authors present a three-terminal thermal transistor with the important feature that the current through the two terminals can be controlled by small changes in the temperature or in the current passing through the third terminal.
Abstract: We report on the first model of a thermal transistor to control heat flow. Like its electronic counterpart, our thermal transistor is a three-terminal device with the important feature that the current through the two terminals can be controlled by small changes in the temperature or in the current through the third terminal. This control feature allows us to switch the device between “off” (insulating) and “on” (conducting) states or to amplify a small current. The thermal transistor model is possible because of the negative differential thermal resistance.

TL;DR: In this article, a threshold-shifting, single transistor memory structure with fast read and write times and long retention time is described, which consists of a silicon field effect transistor with nano-crystals of germanium or silicon placed in the gate oxide in close proximity of the inversion surface.
Abstract: A threshold-shifting, single transistor memory structure with fast read and write times and long retention time is described. The structure consists of a silicon field-effect transistor with nano-crystals of germanium or silicon placed in the gate oxide in close proximity of the inversion surface. Electron charge is stored in these isolated 2-5 nm size nano-crystals which are separated from each other by greater than 5 nm of SiO/sub 2/ and from the inversion layer of the substrate surface by less than 5 nm of SiO/sub 2/. Direct tunneling of charge from the inversion layer and its storage in the nano-crystal causes a shift in the threshold voltage which is detected via current sensing. The nano-crystals are formed using implantation and annealing or using direct deposition of the distributed floating gate region. Threshold shift of 0.3 V is obtained in Ge-implanted devices with 2 nm of SiO/sub 2/ injection layer by a 4 V write pulse of 300 ns duration. The nano-crystal memories achieve improved programming characteristics as a nonvolatile memory as well as simplicity of the single poly-Si-gate process. The V/sub T/ window is scarcely degraded after greater than 10/sup 9/ write/erase cycles or greater than 10/sup 5/ s retention time. Nano-crystal memories are promising for nonvolatile memory applications.

TL;DR: In this paper, the authors describe the simulation of the electrical characteristics of a new transistor concept called the junctionless multigate field effect transistor (MuGFET), which has no junctions, a simpler fabrication process, less variability and better electrical properties than classical inversionmode devices with PN junctions at the source and drain.
Abstract: This paper describes the simulation of the electrical characteristics of a new transistor concept called the ‘‘Junctionless Multigate Field-Effect Transistor (MuGFET)”. The proposed device has no junctions, a simpler fabrication process, less variability and better electrical properties than classical inversion-mode devices with PN junctions at the source and drain. The simulation results indicate that the junctionless MuGFET is a very promising candidate for future decananometer MOSFET applications.

TL;DR: In this article, the authors present a practical guide for understanding basic GaN transistor construction, characteristics, and applications, as well as specific application examples demonstrating design techniques when employing GaN devices.
Abstract: This timely second edition has been substantially expanded to keep students and practicing power conversion engineers ahead of the learning curve in GaN technology advancements. Acknowledging that GaN transistors are not one-to-one replacements for the current MOSFET technology, this book serves as a practical guide for understanding basic GaN transistor construction, characteristics, and applications. Included are discussions on the fundamental physics of these power semiconductors, layout and other circuit design considerations, as well as specific application examples demonstrating design techniques when employing GaN devices.

TL;DR: A new equivalent circuit for the insulated-gate field-effect transistor (IGFET) is described, particularly useful for computer-aided analysis of monolithic integrated IGFET switching circuits.
Abstract: A new equivalent circuit for the insulated-gate field-effect transistor (IGFET) is described. This device model is particularly useful for computer-aided analysis of monolithic integrated IGFET switching circuits. The results of computer simulations using the new equivalent circuit are in close agreement with experimental observations. As an example of a practical application, simulation results are shown for an integrated circuit IGFET memory cell.
