A MOS capacitor with a P-type semiconductor substrate is shown in Fig. 13.92 (b). The top metal terminal, also known as the gate, is at a positive voltage with respect to the semiconductor substrate. We can see that a positive charge will exist on the top metal plate and an electric field will be induced in the direction shown in the figure.

Capacitor | Definition, Function, & Facts
The metal-oxide semiconductor field-effect transistor (MOSFET, pronounced MAWS-feht) is the most common type of field-effect transistor (). They act as electrical switches and amplifiers controlling the amount of electricity that can flow between the source and drain terminals based on the voltage applied to the gate terminal.
The metal–oxide–semiconductor capacitor (MOS capacitor) evolved from the metal–oxide–semiconductor field-effect transistor (MOSFET) structure, which was invented by Mohamed M. Atalla and Dawon Kahng at Bell Labs in 1959. The MOS capacitor became widely used as a storage capacitor in memory chips and as the fundamental …

The actual semiconductor is typically surrounded by a package that protects the device; if you look at a typical PCB, the semiconductor device packages often look like black, multi-legged bugs. Each "leg" is a conducting pin that serves some function for the semiconductor device: for instance, it can be a power supply input, a connection to …

Capacitors are simple passive device that can store an electrical charge on their plates when connected to a voltage source. In this introduction to capacitors tutorial, we will see that capacitors are passive electronic …
Solid-state battery
When voltage is applied to the gate of the MOS capacitor, it creates an electric field which brings free electron charge carriers to the contact surface between the insulator and semiconductor. Initially this creates a depletion region, and then an inversion layer forms where free electrons dominate.
a semiconductor capacitor may also be leaky. That is the case when the equivalent R in parallel with C is too low. This results in resis-tive impedance overwhelming the capacitive impedance, and the C value gets lost in the noise. For devices with ultra-thin D InD ...
