Structural, Optical, and Electrical Properties of Semiconductor Compounds Studied by Means of Inelastic Light Scattering from Phonon, Electron, and Coupled Electron-Phonon Excitations: From Bulk to Nanoscale Structures

摘要

We show results of our systematic investigation by means of quasi-elastic and inelastic laser light scattering (QEILS) of electron- and hole-phonon interactions as well as charge- and spin-density scattering mechanisms from hole gas fluctuations including their overlapping with phonon features by using near infrared excitation of doped bulk p-GaAs and self-assembled InAs/GaAs quantum dot (QD) structures. Additionally, results of our study of CdS and CdSe/ZnS QDs, multi-functionalized by peptides possessing strict affinity to integrins of MDA-MB-435 cancer cells are also presented.
