TFYY54 – Nanophysis
For Y, Fys, MFYS, MPN

6 ECTS points

 

 

Aims

The idea of this course is to give an introduction survey of physics at the nanometer scale. We will explore the physical basis of phenomena that appear when the linear dimension of an object or device shrinks below a micrometer. In addition, the course will cover the experimental techniques currently used to fabricate and characterize nanostructures. A number of already existing applications of “nano-materials”, as well as future possibilities will be also discussed.

 

The course is intended for undergraduate students, but it is open also for International Master Program students and PhD students.

 

Prerequisites

The courses Semiconductor Physics (TFYY47) and Nanotechnology (TFYY87) are desirable, but not compulsory.

 

Organization

32 hours lectures

8 hours laboratory exercises

 

The course is given in English.

 

Course contents

The course consists of three parts.

Part I – Introduction to nanophysics and nanotechnology.

-          scaling laws and limits to smallness

-          quantum nature of nanoworld

-          physical based experimental approaches to nanofabrication and nanoscopy

Part II – Properties and application of dielectric and metal nanostructures.

     -individual nanoparticles – metal and molecular clusters

     -bulk nanostructured materials

     -carbon nanostructures – fullerenes and nanotubes

     -nanomagnets

Part III – Properties and application of semiconductor nanostructures (mainly quantum dots).

-          fabrication of semiconductor quantum dots – nanolithography, self-ordering and Sranski-Krastanov mode epitaxy, selective-area epitaxy

-          electronic and optical properties of quantum dots

-          optical spectroscopy of quantum dots – photoluminescence, photoluminescence excitation, local probe techniques (micro-photoluminescence, near-field scanning optical microscopy, cathodoluminescence)

-          quantum dot based devices – lasers, detectors, solar cells, single-electron transistors, memories.
