Towards Scalable Quantum Computation with Electrically-Gated Silicon Quantum Dot Qubits Susan Coppersmith, University of Wisconsin-Madison [email protected] Dr. Coppersmith’s research currently focuses on the development of quantum information processing devices using electrically-controlled semiconducting quantum dots. This technology has emerged as an attractive candidate for large-scale q...

Thin-film structures can reduce the cost of solar power by using inexpensive substrates and a lower quantity and quality of semiconductor material. However, the resulting short optical path length and minority carrier diffusion length necessitates either a high absorption coefficient or excellent light trapping. Semiconducting nanowire arrays have already been shown to have low reflective losse...

Excellent electrical performance and extreme sensitivity to chemical species in semiconducting Single-Walled Carbon NanoTubes (s-SWCNTs) motivated the study of using them to replace silicon as a next generation field effect transistor (FET) for electronic, optoelectronic, and biological applications. In addition, use of SWCNTs in the recently studied flexible electronics appears more promising ...

Carbon Nanotube Field Effect Transistors (CNFETs), consisting of semiconducting single-walled Carbon Nanotubes (CNTs), show great promise as extensions to silicon CMOS and in large-area electronics. While there has been significant progress at a single-device level, a major gap exists between such results and their transformation into VLSI CNFET technologies. Major CNFET technology challenges i...

The metallic to semiconducting resistivity ratios and the transition temperature sharpness of annealed atomic layer deposited VO2 films on amorphous silicon dioxide are found depend grain size in a closely similar way from previous sputtered or pulse laser work. This occurs because dominance growth compaction processes leads common scaling properties with size. Density functional simulations fi...

This work reviews the use of porous silicon (PS) as a nanomaterial which is extensively investigated and utilized for various applications, e.g., in the fields of optics, sensor technology and biomedicine. Furthermore the combination of PS with one or more materials which are also nanostructured due to their deposition within the porous matrix is discussed. Such nanocompounds offer a broad aven...
