This course will cover the fundamentals of thin films materials science (basics of materials science for thin films, crystallography, quantum mechanics and solid state physics, thermodynamics, kinetics, nucleation and growth, and fundamentals of heat & mass transfer); the case by case examples of thin film material applications will be investigated in growth, processing and characterization context. The growth and thin film forming context will involve epitaxial (homo- & hetero-epitaxy) and non-epitaxial deposition methods; processing will include basic cleanroom processing methods such as deposition, lithography, wet chemical methods in theory, and application specific characterization methods (for imaging, structural, chemical, optical, electrical/magnetic, mechanical applications) will be covered. Obtaining mechanical, electrical, magnetic, optical properties of the resulting thin films and devices will be the main issue. In this context emerging thin-film materials & applications; Metallurgical and protective coatings, Electronic and optic thin film devices, such as HEMT, MOSFET, photo-detectors, solar-cells, LED, LD, VCSEL will be discussed with case studies.
