Electrons, the fundamental charge carriers in solid-state devices, possess three intrinsic properties: mass, charge and spin. Spin is a quantum mechanical property, but can be loosely visualized as a tiny “intrinsic” magnetic dipole moment attached to an electron. In conventional electron...

Group 14 semiconductor nanocrystals exhibit size-dependent optoelectronic properties through the influence of quantum size effects, notably intense photoluminescence (PL). A crucial step toward the realization of their technological potential is the development of effective methods to control the...

Nanomaterials based upon Group 14 elements (i.e., silicon and germanium) are drawing a great deal of attention from researchers since they are biocompatible and exhibit unique optical and electronic properties. Surface functionalization, which is one of the most critical aspects of nanomaterial...

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...

Ultrafast carrier dynamics in silicon nanocrystals (Si NCs) is explored using time-integrated photoluminescence, time-resolved photoluminescence and pump-probe transient absorption spectroscopies. The role of surface oxygen in the optical emission dynamics of dodecyl functionalized Si NCs is...

Quantum dots (QDs) have drawn substantial attention in multidisciplinary research in science, technology, and biomedicine during the last three decades. However, the toxicity of heavy metals and the depleting earth abundance of some elements common to QDs have prompted the development of...
