Multifunctional Devices and Logic Gates With Undoped Silicon Nanowires
Massimo Mongillo, Panayotis Spathis, Georgios Katsaros +2
We report on the electronic transport properties of multiple-gate devices fabricated from undoped silicon nanowires. Understanding and control of the relevant transport mechanisms…
Monolithic growth of ultra-thin Ge nanowires on Si(001)
Jianjun Zhang, Georgios Katsaros, Francesco Montalenti +8
Self-assembled Ge wires with a height of only 3 unit cells and a length of up to 2 micrometers were grown on Si(001) by means of a catalyst-free method based on molecular beam epit…
On the nature of tunable hole g-factors in quantum dots
N. Ares, V. N. Golovach, G. Katsaros +5
Electrically tunable g-factors in quantum dots are highly desirable for applications in quantum computing and spintronics. We report giant modulation of the hole g-factor in a SiGe…
Zero-bias anomaly in a nanowire quantum dot coupled to superconductors
Eduardo J. H. Lee, Xiaocheng Jiang, Ramon Aguado +3
We studied the low-energy states of spin-1/2 quantum dots defined in InAs/InP nanowires and coupled to aluminium superconducting leads. By varying the superconducting gap, Δ, with…
