  • adj. (Of a semiconductor) in which conduction is due to the movement of positive holes rather than electrons.

Etymologies

Sorry, no etymologies found.

Examples

  • Electrons can cross from the spacious boron-silicon (or p-type) layer to the crowded n-type layer, but not the other way.

    Solar energy offers a vast supply of power, but harnessing it is a challenge

  • The crystal wafer is doped with boron to make a p-type semiconductor.

    Photovoltaics

  • Dope silicon with boron, which has three valence electrons, to create a p-type semiconductor.

    Photovoltaics

  • The meat would be "p-type," with an excess of positively charged holes.

    The Transistor

  • There, a Dr. Poganski gave a beautiful demonstration that the selenium rectifier was not a Schottky barrier, but a p-n junction between p-type selenium and n-type CdSe, a true heterojunction - although that term did not exist yet.

    Herbert Kroemer - Autobiography

  • ยท When a p-type material is placed In contact with an e-type rnaterial, an electric field forms at the junction.

    Chapter 11

  • Thyristors general backward blocking backward conducting n-type gate, controlled at anode side p-type gate, controlled at cathode side

    1. Selected Graphical Symbols of Electrotechnology

  • In R&D, we are also developing new technologies, and have put a roadmap and a new process in place to reach 30% of solar cell efficiency utilizing a p-type wafer through innovative process and the device structure research.

  • The junctions between n- and p-type silicon act like valves, stopping current flowing in the wrong direction.

    The Economist: Daily news and views

  • The junctions in a transistor are between bits of silicon doped to conduct electrons known as n-type material, because electrons are negatively charged, and p-type areas doped to conduct positively charged holes in the crystal lattice, which are places where electrons should be, but aren't.
