Abstract:

Reconstructing the surface microtopography through data fusion from a range of microscopies offers a way to provide considerably more information than any one technique alone. This thesis explores several methods for combining the info rmation from different kinds of microscopes including height data, electron images and optical images. Each microscopy has distinct advantages and disadvantages that can be considered in terms of data leakage in the transfer function from the actual sampl e topography to any individual dataset. These leakage paths are identified for a range of microscopies inclu

Abstract:

Using scanning probe microscopy, several studies were carried out to characterize surface topographies and properties. First, utilizing scanning tunneling microscopy (STM), we characterized fullerenes deposited onto gold foils and highly oriented gold films. On gold foils, we found that C₆₀ packed in hexagonally ordered overlayers and that the images showed internal buckyball features that arose from electronic interactions between the molecule and the substrate. On gold films, with an ordered overlayer of methyl isobutyl ketone (MIBK), the isolated C₆₀ molecules showed internal features in a

Abstract:

This thesis presents the development of a high resolution wide field speckle illuminated interferometric surface plasmon microscope. This system is based on a Linnik interferometer and uses a high NA oil immersion objective for the excitation of surface plasmons. The confocal response of the microscope and high surface field enhancement due to surface plasmon excitation lead to high resolution and high contrast of weak surface structures and films. The microscope was also demonstrated in two other modes of operation, a sensing mode where the distributions seen in the back focal plane of the sa

During recent years, new types of materials have been discovered with unique properties. One family of such materials are two-dimensional materials, which include graphene and MXene.

The list of potential applications is long for these new materials. As these materials are almost entire

In an n-type sample with 3X1017 cm-3 carrier concentration, 1 eV upward band bending corresponds to 1.7X1012 cm-2 trapped charge density in the surface states.

One important characteristic of these layered materials is that they are composed of twodimensional (2D) sheets of covalently bonded atoms that are kept together by van der Waals forces.

Abstract:

Since 1982, the Si (111)-(7x7) surface has been extensively studied both theoretically and experimentally with the modern powerful tools of STM and Scanning Tunneling Spectroscopy (STS). In this work, a simple atomic orbital model for the Si (111)-(7x7) surface is developed to simulate the experimental results of STM and STS. Based on Tersoff-Hamann’s theory for the tunneling current, simulations of clean Si (111)-(7x7) constant-current images are presented. The direct, real-space simulated topographic images of the surface are compared to experimental results qualitatively and quantitatively.
