Department of Applied Physics (DAP) is one of the four scientific departments of the Institute of Physics, Silesian University of Technology in Gliwice, Poland. Laboratories and offices of the DAP staff are placed in a building of Faculty of Electrical Engineering, Silesian University of Technology at 2 Krzywoustego street in Gliwice.
DAP scientific activity is focused on studies on thermal properties of solids, electronic properties of semiconductors and semiconductor structures, theoretical complex geometrical optics as well as on scanning microscopy of various types (atomic force microscopy, thermal microscopy, electric field microscopy and Kelvin probe). Moreover, DAP is active in teaching basic physics and specialist courses related to scientific research.
The beginning of DAP dates back to 1971 when the Chair of Technical Physics was transformed into Institute of Physics consisting of six research groups. One of them was „Acoustic methods in studies on semiconductors” and was being managed by Dr Zygmunt Kleszczewski. In 1981 r. the group changed its name to „Research Group of Solid State Acoustics” and was transformed into the Department of Solid State Acoustics in 1984. In 1986, the staff and research topics were extended by problems of semiconductor surfaces and interfaces including studies on metal-oxide-semiconductor (MOS) structures. The department changed its name to the current one on the 1st of Septemeber 2002. Professor Z. Kleszczewski was managing DAP until his death in 2003. The current head of DAP is Professor Jerzy Bodzenta. In September 2009, some staff of the former Department of Electron Technology and of the former Department of Optoelectronics went over to DAP.
