Course Content (Syllabus)
1. Introduction to fundamental concepts related to the structural and electric characterization techniques. 2. “Reciprocal space and Brillouin zone”. Perceptualization of the relation between the diffraction pattern and the reciprocal space and of the diffraction pattern as a Fourier transform. Consolidation of the relation between the real and reciprocal space. Reciprocal space and Brillouin zone for the fcc, bcc, hcp, diamond, sphalerite and wurtzite structures. 3. “Electron microscopy”. Modes of operation of the electron microscope and related interactive software. Imaging with an electron microscope (magnification, resolution). Evaluation of the electron diffraction patterns of a mono- and a poly-crystalline material. Polytype identification. 4. “Study of surfaces and surface defects”. Microscopic surface imaging using the NanoEducator Scanning Probe Microscope. Qualitative and quantitative surface characterization of representative samples (e.g. surface roughness). 5. “Ι-V characteristics”. Characterization of p-n rectifying junctions by means of their current-voltage characteristics. Determination, using proper software, of the diode saturation current, ideality factor, series and parallel resistance. 6. “Conductivity measurements and Hall effect”. Characterization techniques of the electric properties of semiconducting materials and devices. Two- and four-contact resistivity measurements (Van der Pauw).
