IMPACT OF GEOMETRIC SCALING ON SELF-HEATING EFFECTS IN GaAs-BASED GATE-ALL-AROUND FIELD-EFFECT TRANSISTORS
As gate-all-around field-effect transistors (GAAFETs) are scaled toward sub-10 nm gate lengths and nanowire diameters, self-heating effects (SHE) become an increasingly dominant reliability and performance concern, particularly for high-mobility III–V channel materials such as GaAs whose thermal...

CHANGE IN THE WIDTH OF THE VOLUME CHARGE FIELD OF P–N JUNCTION DIODES UNDER THE INFLUENCE OF A MAGNETIC FIELD
In this article, the volt-ampere characteristic of p–n junction diodes under the influence of a magnetic field and the change in the volume charge field parameters were theoretically studied. That is, the effect of the electromotive force (EMF), the Lorentz force, and the change in the distribution...
