Surface texture is important for contact mechanical and tribological phenomena such as the contact area and friction. In this research, three different types of geometrical microstructures were designed and fabricated by pulsed laser surface texturing as semi-symmetric (grooved channel), asymmetric fractal (Hilbert curve), and symmetric...

The performances of microelectronic and optoelectronic devices are often severely limited by high temperatures and insufficient heat management. Therefore, when considering device fabrication and packaging, it is important to select materials based on their thermal performance. The increasing demand for more integrated functionality and...

This review gives a concise introduction to the state-of-art techniques used for surface texturing, e.g., wet etching, plasma etching, laser surface texturing (LST), 3D printing, etc. In order to fabricate deterministic textures with the desired geometric structures and scales, the innovative texturing technologies are developed and extended....

Minimally invasive surgery of the most lethal disease worldwide, coronary artery disease, benefits from better diagnostic tools during the treatment. With this in mind, a novel concept is introduced for intravascular ultrasound on a 360 μm diameter guidewire. The complex manufacture of this medical instrument, and other devices that require...

We report a multiple patterning approach utilizing digital-micromirror-device (DMD)-based grayscale lithography, providing a solution to improve fabrication accuracy for entire target three-dimensional structure. Because DMD-based lithography system consists a projection lens system, better resolution can be obtained around focal position...

In this thesis, I describe experiments aimed at understanding bacterial population dynamics in ecosystems that are spatially structured at the micro-scale. We combine microfabrication and microfluidics to create synthetic ecosystems that have a complex yet well-defined geometry and chemical composition. Bacteria that inhabit such ecosystems can...

This dissertation describes experimental studies on the mechanisms underlying the dynamic response of polyelectrolyte hydrogels when submitted to an external electric potential. In addition, we explore the possibilities of miniaturization and manipulation of responsive gels and other soft matter systems by using microfabrication techniques....

Transmission electron microscopy (TEM) of (de-)hydrogenation reactions is crucial to characterize efficiency of hydrogen storage materials. The nanoreactor, a micromachined channel with 15-nm-thick windows, effectively confines the gas flow to an electron-transparent chamber during TEM of reactions. Realistic experiments require very high...

We present a modular high-vacuum setup for the electrical characterization of single molecules down to liquid helium temperatures. The experimental design is based on microfabricated mechanically controllable break junctions, which offer control over the distance of two electrodes via the bending of a flexible substrate. The actuator part of the...

In this thesis, sub-10 µm fluidic systems with integrated electrodes for pumping and sensing in nanotechnology applications were developed and analyzed. This work contributes to the development of the scanning ion pipette (SIP), a tool to investigate surface changes on the nanometer scale induced by locally administering chemically or bio-active...

Metal microbolometers, used in scanning thermal microscopy, were microfabricated from <20?nm titanium thin films on SiO2/Si3N4/SiO2 cantilevers. These thin films are near the metal-insulator transition regime such that as the film thickness decreases—the resistance increases and the current-voltage characteristics cross over from sublinear to...

Much of the discussion regarding nanotechnology centers around perceived and prosphesied harms and risks. While there are real risks that could emerge from futuristic nanotechnology, there are other current risks involved with its development, not involving physical harms, that could prevent its full promise from being realized. Transitional...

The development of a multi-electron beam system is described which is dedicated for electron beam induced deposition (EBID) with sub-10 nm resolution. EBID is a promising mask-less nanolithography technique which has the potential to become a viable technique for the fabrication of 20-2 nm structures after 2013, as described by the International...
