Difference Between Semiconductor Devices And Transistors

Generally speaking, they are similar, but strictly speaking, there are differences.
🔌Semiconductor devices
Semiconductor devices refer to a very wide range of devices, including ordinary transistors, field effect transistors, and various devices using semiconductor materials, such as LEDs, light-emitting diodes, Gunn diodes, etc.
🔍 Transistor
Transistors generally refer to bipolar transistors. Therefore, the coverage of "Transistor Principles and Design" is relatively narrow.
