摘要： An AFM based technique has been demonstrated for performing highly localized IR spectroscopy on a sample surface. Such a technique implemented in a commercially viable analytical instrument would be extremely useful. Various aspects of the experimental set-up have to be changed to create a commercial version. The invention addresses many of these issues thereby producing a version of the analytical technique that cab be made generally available to the scientific community.

摘要： Described are techniques for obtaining spectroscopic information from sub-micron regions of a sample using a probe microscope. The current invention uses the response of an AFM cantilever at a plurality of frequencies to substantially reduce the impact of background absorption away from the sub-micron region of interest. This innovation substantially improves the quality of spectra for top down illumination of samples that are not suitable for bottoms up illumination of the prior art.

摘要： A method of obtaining submicron resolution IR absorption data from a sample surface. A probe microscope probe interacts with the sample surface while a tunable source of IR radiation illuminates the sample-tip interaction region. The source is modulated at a frequency substantially overlapping the resonant frequency of the probe and may be modulated at the contact resonance frequency of the probe when the probe is in contact with the sample surface. The modulation frequency is continually adjusted to account for shifts in the probe resonant frequency due to sample or other variations. A variety of techniques are used to observe such shifts and accomplish the adjustments in a rapid manner.

Some of the described devices and methods are also useful for measuring infrared absorbances and compiling spectral and chemical maps of surfaces. Also described are microcantilever having reduced harmonic frequencies when operating in contact mode. Some of the described microcantilevers comprise an internal resonator configured to vibrate substantially independent of friction between the microcantilever tip and a surface when the microcantilever operates in contact mode. A number of the described devices and methods are useful for monitoring pulsed forces with enhanced sensitivity.

摘要： Dynamic IR radiation power control for use in a nanoscale IR spectroscopy system based on an Atomic Force Microscope. During illumination from an IR source, an AFM probe tip interaction with a sample due to local IR sample absorption is monitored. The power of the illumination at the sample is dynamically decreased to minimize sample overheating in locations/wavelengths where absorption is high and increased in locations/wavelengths where absorption is low to maintain signal to noise.
