Doping (semiconductor)
Doping (semiconductor) In semiconductor production, doping is the intentional introduction of impurities into an intrinsic semiconductor for the purpose of modulating its electrical, optical and structural properties. The doped material is referred to as an extrinsic semiconductor. Small numbers of dopant atoms can change the ability of a
9.7: Semiconductors and Doping - Physics LibreTexts
The electric current of a doped semiconductor can be due to the motion of a majority carrier, in which holes are contributed by an impurity atom, or due to a minority carrier, in which holes are contributed purely by thermal excitations of electrons across the energy gap.
- What is semiconductor doping?
- In processing of modern semiconductor devices, doping refers to the process of introducing impurity atoms into a semiconductor wafer by ion implantation. The purpose of semiconductor doping is to define the number and the type of free charges in a crystal region that can be moved by applying an external voltage.
- How has doping changed the electronics industry?
- Doping of semiconductors has revolutionized the electronics industry, enabling the development of smaller, more efficient, and more powerful electronic devices. As technology continues to advance, the demand for more efficient and higher-performing electronic devices will only continue to grow.
- What happens if a semiconductor is doped?
- In most cases many types of impurities will be present in the resultant doped semiconductor. If an equal number of donors and acceptors are present in the semiconductor, the extra core electrons provided by the former will be used to satisfy the broken bonds due to the latter, so that doping produces no free carriers of either type.
- What is a p-type doped semiconductor?
- The most common p-type doped semiconductor is boron. The process of doping can be achieved through different methods, such as diffusion or ion implantation. In diffusion, a dopant source, usually in the form of a gas or solid, is introduced to the semiconductor and allowed to diffuse into the material.
- What is diamond doping?
- Precisely doped diamond semiconductors definitely lead to the creation of diamond-based electronic devices with performance characteristics that dramatically exceed those of conventional semiconductors such as Si or GaAs . In general, impurity doping for such small amounts of dopants is performed by thermal diffusion and ion implantation.
- How do semiconductors become useful electronic materials?
- It is only through doping that semiconductors become useful electronic materials. Recent studies have revealed an unconventional way to achieve doping through surface engineering. Doping of semiconductors is usually achieved by incorporating atoms of appropriate elements into the host lattice of the semiconductor.
