This special ability makes semiconductors the perfect brains for electronic devices. Circuits of small semiconductor switches, called transistors, are the heart of computer chips, and enable them to do math and run programs. 半导体使电子产品变得更小、更快、更可靠。 但是,到底是什么使得半导体既能导电...
25. What are n-type and p-type semiconductors? 相关知识点: 试题来源: 解析 Ans:n-type semiconductor is obtained by doping of the crystal of a group 14 elementsuch as Si or Ge, with a group 15 element such as P or As(pentavalent).Conductivity increases due to negatively charged electrons...
Semiconductors are essential features of modern electronics, from computers and smart phones to bank cash machines and trains. They are used in the makeup of transistors.
form A P-type semiconductor is formed when a trivalent element (such as boron) is added to a pure silicon crystal to replace the silicon atoms in the lattice. In P-type semiconductors, the holes are many, the free electrons are few, and the conduction is mainly by holes. Because the am...
Run the computer and all its programs. ASIC Application-specific integrated circuit What they do: One thing very quickly, including deep learning, encryption and network processing. Semiconductors are everywhere The average American adult spends more than 12 hours a day using electronics, such as com...

Semiconductors: Those elements whose conductivity increases with an increase in temperature are called semiconductors. There are two types of semiconductors: Intrinsic semiconductors: Pure substances that are semiconductors are called intrinsic semicon
Semiconductors are of 2 Types: AnN-type semiconductoris one that carries current in the form of negatively-charged electrons. This is very similar to conduction of current in a wire. AP-type semiconductoris one that carries current predominantly as electron deficiencies called holes. A hole has ...
Solids which have conductivity inbetween those of conductors and insulator , i.e., ranging from 10^(-6) to 10^4 "ohm"^(-1) m^(-1) are called semiconductors. The two main types are n-type and p-type.
