We present the characterization of close-spaced linear dangling bond structures, or dangling bond chains, two to seven dangling bonds long, on a hydrogen terminated silicon (100)-2x1 surface using a scan- ning tunnelling microscope. Constant height differential conductance maps reveal their local...

Dangling Bonds (DBs) on the silicon surface exist when a silicon atom lacks a bonding partner, resulting in a localized orbital which is not involved in any chemical bonds. On the hydrogen-terminated Si(100) surface, such DBs introduce a mid-gap state. DBs can be created on this surface by the...

The field of plasmonics has offered the promise to combine electronics and photonics at the nanometer scale for ultrafast information processing speeds and compact integration of devices. Various plasmonic waveguide schemes were proposed with the potential to achieve switching functionalities and...

Silicon Nanoparticles from the Inside Out: Exploring the Internal Structure of Silicon Nanoparticles and Its Impact on Their Photoluminescence
DownloadFall 2020
Silicon nanoparticles (SiNPs) have garnered significant attention as a biologically compatible alternative to traditional quantum dots. SiNPs are well suited for a wide range of applications due to their photoluminescence (PL) and chemical properties. These advantageous properties can be...

Nanoscale lithography on silicon is of interest for applications ranging from computer chip design to tissue interfacing. Block copolymer-based self-assembly, also called directed self-assembly (DSA) within the semiconductor industry, can produce a variety of complex nanopatterns on silicon, but...

Silicon nanocrystals (SiNCs) have been suggested as promising candidates for bioimaging because of their abundance, biocompatibility, and stable photoluminescent properties. However, “naked” SiNCs are insoluble in water and very reactive. As a result, NC surface functionalization is necessary to...

The elements of Group 14 show an extensive range of chemical behaviors. Lying at the boundary between metals and non-metals, some members of Group 14, namely silicon and germanium, are intermediate in their properties. These semiconductors are extremely important in science and technology. Si,...

This thesis will discuss the charge dynamics of dangling bonds (DBs) on the hydrogen terminated Si(100) surface under the effects of temperature and perturbations from local electric fields. The experimental methods are then extended towards DB chains. Electronic time resolved imaging techniques...
