Introduction to thin film science and technology

 Thin film science and technology addresses the fundamentals behind the synthesis, characterization, and application of thin film materials. For the purpose of this course, we will define as “thin films” materials which are homogeneous, have one dimension comparable in size to the wavelength of the visible light, and much smaller than the other two dimensions.

Throughout the course we will explore two classes of methods for the synthesis of thin films: chemical and physical methods. Here, the difference between chemical and physical methods depicts whether a chemical transformation occurs (chemical methods) or not (physical methods) during the thin film preparation. These methods will focus on the preparation of dielectric materials, such as linear, non-conjugated polymers, and semiconductors, such as conjugated polymers, 2D materials and more.

After a brief overview of the principal spectroscopic, microscopic, and surface characterization methods, we will dive into classical and forthcoming applications of thin film materials. Here, we will explore the advantages of exploiting thin films and multilayered materials and their application in optics, photonics, and energy devices.

In light of the importance of preparing thin films, two sessions will be dedicated to the synthesis of thin films in our laboratories. In these sessions we will address the synthesis of polymer thin films by spin coating and chemical vapor deposition. The assessment will be in form of a report on these practical lab experiences. The course and the reports are in English language.
