PtSi Clustering In Silicon Probed by Transport Spectroscopy
Massimo Mongillo, Panayotis Spathis, Georgios Katsaros +4
Metal silicides formed by means of thermal annealing processes are employed as contact materials in microelectronics. Control of the structure of silicide/silicon interfaces become…
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…
Joule-assisted silicidation for short-channel silicon nanowire devices
Massimo Mongillo, Panayotis Spathis, Georgios Katsaros +3
We report on a technique enabling electrical control of the contact silicidation process in silicon nanowire devices. Undoped silicon nanowires were contacted by pairs of nickel el…
Observation of spin-selective tunneling in SiGe nanocrystals
G. Katsaros, V. N. Golovach, P. Spathis +6
Spin-selective tunneling of holes in SiGe nanocrystals contacted by normal-metal leads is reported. The spin selectivity arises from an interplay of the orbital effect of the magne…
A Josephson Quantum Electron Pump
F. Giazotto, P. Spathis, S. Roddaro +4
A macroscopic fluid pump works according to the law of Newtonian mechanics and transfers a large number of molecules per cycle (of the order of 10^23). By contrast, a nano-scale ch…
Cooling electrons from 1 K to 400 mK with V-based nanorefrigerators
O. Quaranta, P. Spathis, F. Beltram +1
The fabrication and operation of V-based superconducting nanorefrigerators is reported. Specifically, electrons in an Al island are cooled thanks to hot-quasiparticle extraction pr…
