Semiconductors: Introduction

Semiconductors: Introduction

Let us start with the brief recap of what we learned in the last class. So, last class, we said the based on resistivity, we can classify materials into three types – conductors or metals, semiconductors and insulators. We were trying to explain the vast difference in resistivity or conductivity between metals and semiconductors. So,…

Optoelectronic devices: Introduction

Optoelectronic devices: Introduction

In the last few classes, we have looked at Electronic devices. So, we first started looking at a Metal Semiconductor contact, forms your Schottky junction or an Ohmic junction. We then looked at p-n junctions and then finally, transistors. We saw that there were different kinds of transistors, but we focused on the metal oxide…
