Function and Applications
Easy to use scanning tunneling microscope to image conducting surfaces and to investigate effects and characteritics on atomic and molecular scale. A variety of experiments in the fields of Material Sciences, Solid State Physics/Chemistry, Nanotechnology and Quantum Mechanics can be performed. For example: micro- and nano morphology of surfaces, nano structures, imaging of atoms and molecules, conductivity, tunneling effect, charge density waves, single molecule contacts, and nanostructuring by self organisation (self assembled monolayers).
