Electronic transport in nanometre-scale silicon-on-insulator membranes

Article Abstract:

The silicon-on-insulator system consists of a layer of single-crystalline silicon supported on a silicon dioxide substrate and it promises to become the platform for future high-speed electronics as well as for a range of sensor technologies. The development of unusual electronic properties with decreasing layer thickness is particularly important for silicon microelectronic devices.

The interface between silicon and a high-k oxide

Article Abstract:

The principle calculations of the formation of the interface between silicon and strontium titanate and its atomic structure are described. The study reveals that atomic control of the interfacial structure by altering the chemical environment can dramatically improve the electronic properties of the interface to meet technological requirements.

The birth of a quasiparticle in silicon observed in time-frequency space

Article Abstract:

Research describes the coherent response of silicon to excitation with laser pulse and the generation of a quasiparticle. Data indicate that interference effects cause coherent phonon generation and dressing the phonon by electron-hole pair excitations leading to the formation of the quasiparticle.
