Inhalt
Oberflächenabbildung mit Rastersondenmikroskopie/Imaging surfaces with scanning probe microscopyThe lecture will introduce into the basic principles and the physics behind scanning tunneling microscopy (STM) and scanning/atomic force microscopy (AFM).
I. Scanning tunneling microscopy
I.A Basics (Quantum mechanics, tunneling effect, s-wave model, resolution limits)
I.B Experimental details (Instrumentation, mechanical decoupling, feed-back loops)
I.C Spectroscopy (Small/large field models, surface states, image potential states, impurity spectroscopy, surface alloys)
I.D Thermo-voltage (Seebeck effect, noise spectroscopy)
I.E Spin-polarized STM ( ferromagnets. Antiferromagnets, superconductors)
I.F Time-resolved STM (Instrumentation, Dynamic processes)
II Scanning force microsocpy
II.A Basics (History, instrumentation, overview of operation modes)
II.B tip-sample forces (van der Waals, electrostatic, chemical forces, contact mechanics, force calibration)
II.C Surface topography imaging (contact mode, tapping mode, physe modulation/frequency modulation)
II.D Noise limitations/atomic resolution imaging
II.E Surface potential mapping (Kelvin Probe force microscopy)
II.F Measuring nanoscale dynamics (High-speed AFM, time-resolved pump probe techniques)
