Charge Pumping Techniques

Definition

Charge pumping techniques are methods used in electronic devices to inject charge carriers, such as electrons or holes, into a semiconductor material to enhance device performance. This technique is particularly important in the context of nanoscale devices, where traditional methods of biasing and voltage application may not be effective due to the small dimensions and unique properties of nanomaterials. Charge pumping helps in improving the efficiency, speed, and reliability of nanodevices by managing the flow of charge carriers effectively.
