We explore the performance of a scanning near-field infrared microscope, which works by scattering tightly focused CO2 laser radiation (lambda = 10 microm) from the apex of a metallized atomic force microscope tip. The infrared images of test samples prove a spatial resolution of 30 nm and are free of topographical and inertial artefacts, thus they should(More)
We have enhanced the apertureless scattering-type scanning near-field optical microscope by two improvements which together achieve a recording of the true near field without any height-induced artefact. These are the use of interferometric detection of the scattered light on one hand, and the use of higher-harmonic dither demodulation of the scattered(More)
In the present study an improved method for 2D doping profiling of semiconductor device structures is presented. The method combines the capabilities of scanning capacitance microscopy (SCM) with the advantages of intermittent contact atomic force microscopy (IC-AFM) and is called intermittent contact scanning capacitance microscopy (IC-SCM). Compared with(More)
The introduction of the new ÖBB management operation system has to result in an increase in reliability and quality. At the same time, operational costs are to be reduced. These goals can only be achieved by concentrating the responsible staff on a few locations. Consequently, the traditional train supervision has to be replaced by a technical solution, the(More)
Meanings of pluralism in different disciplines – Meaning in jurisprudence, esp. European Court of Human Rights – Feature of society and idea of society – Individual freedom v. group existence – Politics, religion, education – Pluralism as expression of rights and as guarantee of rights – Rejection of legal pluralism – Contradiction of elitist theory – State(More)
