Abstract : Research highlights describing this include: (1) Improving the resolution of scanning probe microscopy in order to enhance the imaging quality of nanostructure materials. In particular, disturbance suppression schemes were implemented with the scanning tunneling microscope (Section I) and with conventional tapping mode (Section II). (2) Development of an ultrasensitive mass sensor known as the suspended microchannel resonator. As described in Section III, the quality factor (and hence mass resolution) was improved by nearly ten-fold with a wafer-scale vacuum packaging technique that was developed at MIT's Microsystems Technology Laboratory.
