FFFN35 - Physics of low-dimensional structures and quantum devices

Course info fall 2018

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

Note: The project reports can now be found here where the schedule also is. You should read the other students reports before the presentations. This will give a better experience tomorrow.

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. Ville Maisi

Slides on quantum dots (password protected)

Slides on Chapter 6 (password protected)

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.

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

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

Material about band gaps

Slides on resonant tunneling

Computer exercise

On Friday, 16/11, there will be a compulsory computer exercise at 13.15 in K204. 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.


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 Sven Dorsch as supervisor. 


Part of the course involve a project that will be performed during about one week. Most of the projects will be performed week 50. Presentation on Dec. 20 at 13.15 in K:404.

Instructions for the projects, including how the report should be can be found here. Please read through the project topics and rank the five that you like best. Enter your choices here where the project assignments are now given. You were assigned a project close to your choices. Give your report to your supervisor on Tuesday for comments such that MEP can have the final reports in pdf on Wednesday noon, 19/12. 

2018-11-28: Project topics are now available

2018-12-19: The projects can be viewed and probably downloaded from here. The schedule is also there.


Problem set for the exercise on 9/11: 1.1, 1.2, 1.3, 1.6, 1.9, 1.11 in the book.

Problem set for the exercise on 16/11: 1.18, 2.1, 2.7, 2.8 in the book.

Problem set for the exercise on 23/11: week 3.

Problem set for the exercise on 30/11: 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 7/12 and 14/12: Davies 6.5, 6.12, 6.13, 3.5, 3.6, 3.8, 3.9, 7.1, 7.3, 7.4. 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.


The exam is 17/1 at 08.00 in Sparta D. You are allowed the book, the documents "Text on Quantum Dots" and "Optical transitions in low-dimensional structures", and a calculator on the exam. No handwritten notes are allowed.
