Do you know what a semiconductor is? How many types does it have？
Basic knowledge of semiconductorsAccording to the electrical conductivity of objects, natural substances can be divided into three categories: conductors, insulators and semiconductors. Generally, substances with a resistivity of less than 10-4Ω. cm are called conductors, and mainly metal materials such as gold, silver, copper, iron, etc. are good conductors. Substances with a resistivity greater than […]
