What is Drain Induced Barrier Lowering? Ideally, drain current Ids should be constant i.e. independent of Vds in saturation region. In reality, Ids increases with Vds in saturation region because of the following two regions: 1) Channel length modulation: As Vds increases, length Leff decreases, hence current increases. 2) Drain Induced Barrier Lowering: As Vds increases, Vt decreases, hence current increases. Drain Induced Barrier Lowering (DIBL) is a decrease in threshold voltage

electrons forming a lowdimensional layer, residing in a semiconductor film called a quantum well. The layer of electrons is called low-dimensional because it forms a quasi-two-dimensional electron system, a layer of electrons so thin that the third dimension is negligible. To perform ACT, a sound wave, called a surface acoustic wave (SAW) due to its propagation in two dimensions, is passed through the semiconductor film. Properties of the semiconductor result in an acoustoelectric

wafer is a thin slice of silicon crystal used in the fabrication of integrated circuits and other micro devices. Silicon is widely used in the semiconductor industry because it remains a semiconductor at higher temperatures than other semiconductor materials and because its native oxide is easily grown. Once grown its native oxide forms a better semiconductor/dielectric interface than other materials. The purpose of this article is to give a brief and basic explanation of the many different silicon

Everyday experience has already taught us a lot about the electrical properties of metals and insulators. But the same cannot be said about “semiconductors”. What happens when we connect a battery to a piece of a silicon;
