This book was released on 2009 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis reports on developing a femtosecond electron diffraction technique and its application in following the structural changes associated with photoexcited Si. Time resolved electron diffraction is capable in principle of capturing transient structures of photoinduced phenomena with femtosecond time resolution. In practice, however, the time resolution is severely limited by the broadening of electron pulses due to space-charge forces. Another technical difficulty lies in that diffraction in transmission geometry requires samples that are semi-transparent to electrons. These experimental challenges were dealt with using innovative engineering and software development, and novel nanofabrication methods. Subsequently, a robust highly automated experimental setup was established, and 50 nm free-standing membranes of polycrystalline Si were nanofabricated. These membranes were first excited below damage threshold with 387 nm light, at an absorbed fluence of 5.6 mJ/cm2. The observed loss of intensity and associated dynamics under these conditions are related to the Debye-Waller effect as the lattice heats up through electron-phonon processes. At high excitation levels, greater than ∼6% of the valence electron density, the crystalline structure of the lattice was lost in 500 fs. This observed time scale is indicative of an electronically driven order-to-disorder phase transition due to an abrupt change in the potential-energy landscape of the lattice. In addition, it was discovered that the high sensitivity of the electron diffraction process to shear-type deformation in single crystals makes the technique ideal to the generation and detection of coherent acoustic phonons. Longitudinal and shear acoustic phonons were subsequently resolved in (001)-oriented Si crystals. This study constitutes the first direct observation of shear phonons in symmetrically cut crystals, in sharp in contrast to the all-optical methods that rely on crystals asymmetrically cut at 20° to enhance the amplitude of the shear mode in order to detect its displacements.

Available in PDF, EPUB and Kindle. Book excerpt: Epitaxial integration of III-V semiconductors on silicon substrates has been desired over decades for high application potential in microelectronics, photovoltaics, and beyond. The performance of optoelectronic devices is still severely impaired by critical defect mechanisms driven by the crucial polar-on-nonpolar heterointerface. This thesis reports almost lattice-matched growth of thin gallium phosphide films as a viable model system for III-V/Si(100) interface investigations. The impact of antiphase disorder on the heteroepitaxial growth surface provides quantitative optical in situ access to one of the most notorious defect mechanisms, even in the vapor phase ambient common for compound semiconductor technology. Precise control over the surface structure of the Si(100) substrates prior to III-V nucleation prevents the formation of antiphase domains. The hydrogen-based process ambient enables the preparation of anomalous double-layer step structures on Si(100), highly beneficial for subsequent III-V integration.
