FFF042 - Physics of low-dimensional structures and quantum devices

Course info fall 2015

Welcome to the home-page for the course in "The physics of low-dimensional structures and quantum devices".

Recent changes:

Clarification concerning allowed documents on the exam: You are allowed the book, the documents "Text on Quantum Dots" and "Optical transitions in low-dimensional structures", and a calculator on the exam. As indicated in the email with the example exam, you are NOT allowed handwritten notes (even though the example exam says so). 

An example exam has been emailed to all course participants. Please contact the lecturers if you have not received this email with the exam. 

You can now find the project reports below. 

Here is a schedule for the project presentations.

Now all the project descriptions can be found below.  

On Tuesday, 10/11 I will bring sheets so you can sign up for the labs. MEP.

The course book is: The physics of low-dimensional structures and quantum devices by John H. Davies and you should order it yourselves from e. g. bokus or buy it at KFS.

The initial part and the optics part will be lectured by Prof. Mats-Erik Pistol 

The transport part will be lectured by Dr. Martin Leijnse

Coulomb Blockade article: part 1part 2 (not required reading, but if you think it helps...)

The material on quantum dots is not included in Davies, you should instead read: Text om Quantum Dots. The most important material is on pages 1 to 9, but if you are interested you can read up to mid-page 12. This document is allowed during the exam.

Absorption in quantum wells. The lecture notes can be found here, in a more complete form. This document is allowed during the exam.

Computer exercise

On Friday, 13/11, there will be a compulsory computer exercise at 13.15 in H212. The instructions for the exercise can be found here. Note that there is a problem that you should do before the exercise begins. The matlab programs that you need can be found here: perm.mdos.m.

Labs

General instructions for the labs can be found here. You must read these instructions.

The instructions for the PLE-lab can be found here and here.

The instructions for the Coulomb blockade lab is here. Note that there are preparation questions you should do in advance. You should meet for the lab in k-space (Berzeliuslab) a few minutes before the lab starts, and the lab itself is in Berzeliuslab, with Ali Nowzari as supervisor. 

Project

Part of the course involve a project that will be performed during about one week. Most of the projects will be performed 7-11/12.

Here is a file with descriptions of all projects.

Here is a link to a google form where you can rank your project choices: https://docs.google.com/forms/d/1nMX5f5QFDI7Y4dS4ISpz68apG0Vql-NmJmhI6qq9ifA/viewform?usp=send_form

Deadline for choosing a project is Tuesday December 1 at 08:00.

Here is a list of project assignments.

Instructions for the projects, including how the report should be can be found here

Here is a schedule for the project presentations on Wednesday, December 16 in room K404.

Here are the project reports: project 1, project 2, project 3, project 4, project 5, project 6, project 7, project 8, project 9, project 10, project 11, project 12.

Exercises

Problem set for the exercise on 6/11: 1.1, 1.2, 1.3, 1.6, 1.9, 1.11 in the book.

Problem set for the exercise on 13/11: 2.1, 2.8, 3.5, 3.6, 3.8, 3.9 in the book.

Problem set for the exercise on 20/11: week 3.

Problem set for the exercise on 27/11: This file contains a problem with Coulomb diamonds. Davies 6.9 and (if you have the time and patience) 6.1.

Problem set for the exercises on 4/12 and 11/12: Davies 6.5, 6.12, 6.13, 7.1, 7.3, 7.4, 7.5, 8.11. In problem 6.12 you should ignore the last question about the current, and in problem 7.1 you need to find an integral and you can ask the supervisors for its value. The last part of problem 7.1 is interesting but time-consuming, we suggest to leave it until you've done 8.11. 

Exam

The exam is 15/1 at 08.00 in H421. You are allowed the book, the documents "Text on Quantum Dots" and "Optical transitions in low-dimensional structures", and a calculator on the exam.
