IntroductionIntroduction

• Attendance policy

– Four absences will be treated as course failure (F)

– Three tardiness will result to one absence

– If there are any special reasons for your absences (such as

military services or illness), please let me know in advance.

– The use of cell phone during class hours will result to one

absence.

§ “A semiconductor is a material that has a resistivity value between that of a conductor and an insulator”

§ Current can be carried either by the flow of electrons or by the flow of holes

§ Silicon is used to create most semiconductors commercially

§The conductivity of semiconductor material can be drastically changed by adding other elements, called “impurities”

Metal - Cu

Semiconductor - Si
