Higher Physics - Unit 3 - Semiconductors Introduction

I created my own revision notes for all units of the Higher Physics course.

These are revision notes for part of the 3rd unit (Radiation and Matter), section 3 (Optoelectronics and Semi-conductors). I've uploaded all the subsections of this section in different files as they are otherwise too large.

Semiconductors Introduction covers:
• Examples of conductors, semiconductors and insulators
• Semiconductors and resistance
• Doping meaning
• Semiconductor and electrons
• n-type semiconductor
• p-type semiconductor
