Grain growth in Pt microheaters subjected to high current density under constant power
Ottó Elíasson, Gabriel Vasile, Snorri Ingvarsson
When nm thick Pt microheaters of lateral dimensions m are subjected to high electric power their resistance rises, as expected. Following an initial ris…

Orbital and spin magnetization of a confined electronic system in the transition between a quantum dot and a ring
Gabriel Vasile, Vidar Gudmundsson, Andrei Manolescu
In order to understand the orbital and spin magnetization of a confined electronic system we analyze these ground state properties in the transition from a quantum dot to a quantum…
