Anotation:
Modern semiconductor devices and integrated circuits are based on unique energy band, carrier transport, and optical properties of semiconductor materials. Students will be prepared to choose these properties for operation of semiconductor devices. Emphasis is on quantum mechanical foundations of the properties of solids, energy bandgap engineering, semiconductor statistics, semi-classical transport theory (Boltzmann transport equation), carrier scattering, electro-magneto transport effects, high field ballistic transport, optical absorption, and radiative and non-radiative recombination. These princliples will be studied on the experimental basis as well. Students will prepare own structures according their thesis subjects and they will characterise them during their individual projects
Study targets:
To gain the theoretical knowledge and practical applications of modern technologies, nanostructures and material characterisation methods.
Content:
Introduction into theory of nanostructures and quantum based devices in electronics. Application of this knowledge in device design, preparation and characterisation in framework of individual projects in connection with the student's research work.
