3S370: Introduction nanotechnology
prof.dr. E.P.A.M. Bakkers - Fontys S2 2.22 - tel: 4105 - email@example.com
The course is intended to give a general introduction into state-of-the-art nanotechnology for students with either a physics or a chemistry background at the Bachelor level. Students will be taught the basics of electronic properties in (nanostructured) solid state systems and get an introduction into the principles of organic macromolecular chemistry. The lectures will give a first glimpse onto advanced techniques for the creation and manipulation of nanostructures such as lithographic methods, scanning probe techniques, and molecular bottom-up approaches and the peculiar physics that can occur in nanostructured materials.
3S260: Introduction to Semiconductors and their applications
dr. J.E.M. Haverkort - Fontys S2 2.06 - tel: 4205 - j.e.m.haverkort@ tue.nl
In this course, we will introduce the elementary properties of bulk semiconductors and of the artificial low-dimensional semiconductors such as quantum wells, superlattices and quantum dots which are frequently used for telecommunication applications. After an introduction of the bandstructure of bulk semiconductors, we will treat the principle of quantum confinement and miniband formation. Subsequently, we will focus on the optical properties of these semiconductors, including impurity transitions, excitons and photoluminescence spectra. In the second part of this course, we will first introduce the pn-junction and introduce the transistor at an elementary level, including the metal-semiconductor junction. The final part of this course deals with an introduction into semiconductor lasers and electro-optic modulators.
Topics: Band structure, Low-dimensional semiconductors, impurities and excitons, spectroscopy of bulk, QW and QD structures, carrier cooling, intrinsic and extrinsic carrier concentration, p-n junctions, transistors, metal-semiconductor junction, interband absorption, semiconductor lasers.
3S280: Semiconductor nanophysics
prof.dr. P.M. Koenraad - NLd 2.10 - tel: 4105 - p.m.koenraad@ tue.nl
Modern epitaxial growth techniques allow the construction of semiconductor materials in which the freedom of motion is limited to 2, 1 or even 0 dimensions. In such structures quantum effects play an important role and lead to very interesting physics (Nobel prizes in Physics 1985, 1998 and 2000). Quantum effects which are due to the reduced freedom of motion can also play an important role in modern commercial semiconductor devices. Especially in modern optical communication networks low-dimensional semiconductor structures have become essential. This course starts with a general introduction on semiconductor materials after which the quantum effects in low-dimensional semiconductor structures will be discussed in detail. The course will follow the material discussed in the book ¿The physics of low-dimensional semiconductors" of J. H. Davies.

Information processing technology based on controlling the flow of photons is becoming increasingly more important in comparison to electronics. Advances in fiber-optical communication technology, required by ever demanding Internet applications, are dependent on smaller and faster optical devices. The ultimate control of light on the scale of its wavelength is achieved with nanoscale structuring of optical materials. Nanophotonics will eventually also enter domains that now are still exclusively electronic, such as computer interconnects. In this course, an introduction will be given to the field of Nanophotonics. An overview will be presented of the application areas. A survey of materials suitable for optical functionalities is given, including passive dielectrics, active, Er-doped dielectrics or semiconductor nanostructures. An important part of the course is devoted to Photonic Crystals: materials with periodically varying refractive index on the scale of the wavelength. Electromagnetic wave propagation in periodic media is shown to lead to the key concept of photonic crystals, the photonic bandgap, analogous to the electronic bandgap in semiconductors. Properly designed defects create the functionalities in these systems like waveguides, cavities, etc. Fabrication methods in one, two and three dimensions will be presented. New research and application domains, accessible with nanophotonic devices will be addressed, including negative refraction and semiconductor cavity Quantum Electrodynamics. Finally, an introduction is given to the field of plasmonics, dealing with the optical properties of metallic nanostructures.
