ABSTRACTScanning Nonlinear Dielectric Microscopy (SNDM) is the method for observing ferroelectric polarization distribution, and now, its resolution has become to the sub-nanometer order, which is much higher than other scanning probe microscopy (SPM) methods for the same purpose. Up to now, we have studied high-density ferroelectric data storage using this microscopy. In this study, we have conducted fundamental experiments of nano-sized inverted domain formation in LiTaO3 single, and successfully formed inverted dot array with the density of 1.5 Tbit/inch2.

In this paper, we propose a large deflection piezoelectric microrobotic manipulator with the ability to self-calibrate displacement and sense its position. Such a manipulator should be applicable to scanning probe microscopy, nanolithography, data storage, biological probing in murky aqueous environments, and the like. Previous devices for such applications are limited in dexterity, range of motion, frequency response, positional calibration, or require environmental cleanliness. Our device has a three novel attributes, which are: an ability to achieve large deflections with greater than one degree of freedom (DOF); an ability to self-calibrate it displacement; and an ability to sense its position after actuation or prescribed displacement. Through simulation we demonstrate independent 3 DOF motional control (validated experimentally), positional sensing and self-calibration, and dynamic response.

Ultra Precision

Several approaches for the precision control of micro-scale positioning mechanisms, or MEMS nanopositioners, are presented along with initial experimental results which demonstrate nano-scale positioning resolution. The MEMS nanopositioners discussed in this paper are novel precision mechanisms comprised of a bent-beam thermal actuator and a flexure mechanism for each degree of freedom (DOF). These mechanisms can be used for a host of ultra-precision positioning applications, including nanomanipulation, scanning probe microscopy, high-density data storage and beam steering arrays. Concentrating on a 1 DOF MEMS nanopositioner, empirical static and dynamic models have been derived using characterization data obtained from experiments with optical and laser probe microscopes. Based on these models, three control approaches have been developed: 1) a quasi-static nonlinear open-loop controller, 2) a nonlinear forward compensator, and 3) a nonlinear PI controller. Simulation and initial experimental results are presented, and the benefits of each of these approaches are discussed.

Nanostructures, which have characteristic dimensions that are difficult to achieve by conventional optical lithography techniques, are finding ever-increasing applications in a variety of fields. High resolution, reliability and throughput fabrication of these nanostructures is essential if applications incorporating nanodevices are to gain widespread acceptance. Owing to the minimal thermal and mechanical damage, ultra-short pulsed laser radiation has been shown to be effective for precision material processing and surface micro-modification. In this work, nanostructuring based on local field enhancement in the near field of a Scanning Probe Microscope (SPM) probe tip irradiated with femtosecond laser pulses has been studied. High spatial resolution (~10–12nm), flexibility in the choice of the substrate material and possibility of massive integration of the tips make this method highly attractive for nanomodification. We report results of nanostructuring of gold thin film utilizing an 800nm femtosecond laser system in conjunction with a commercial SPM in ambient air. Further, Finite Difference Time Domain (FDTD) simulation results for the spatial distribution of the laser field intensity beneath the tip are presented. Potential applications of this method include nanolithography, nanodeposition, high-density data storage, as well as various biotechnology related applications.
