Properties of semiconductors and related nanostructures

MSE-484 / 5 credits

Teacher: Piazza Valerio

Language: English

Summary

This course explains the origin of optical and electrical properties of semiconductors. The course elaborates how they change when the semiconductors are reduced to sizes of few nanometers. The course provides also the basis to use software to calculate the properties of hetero/nanostructures.

Content

We will discuss the relation between the size and the fundamental properties of semiconductor materials. We will as well relate the added functionality related to the low dimensionality with the technological applications.
1. Introduction
2. Basic concepts of bulk semiconductors
3. Fabrication and synthesis techniques
- Top-down versus bottom-up
- Top-down fabrication techniques
- Bottom-up synthesis techniques from the vapor phase (MBE,CVD...)
4. Electronic transport properties of bulk and low dimensional semiconductors
5. Optical properties of bulk and low dimensional semiconductors
6. Simulations of the properties of hetero and nanostructures with Nextnano3
