Targets of isotropic graphite and hexagonal boron nitride were exposed to short pulses of uranium ions with ∼1 GeV kinetic energy. The deposited power density of ∼3 MW/cm³ generates thermal stress in the samples leading to pressure waves. The ve

Atomistic simulation of the FEBID-driven growth of iron-based nanostructures

Autor: Alexey Prosvetov, Alexey V. Verkhovtsev, Gennady Sushko, Andrey V. Solov'yov

The growth of iron-containing nanostructures in the process of focused electron beam-induced deposition (FEBID) of Fe(CO)$_5$ is studied by means of atomistic irradiation-driven molecular dynamics (IDMD) simulations. The geometrical characteristics (

The fast evaporative cooling ofmicrometer-sizedwater droplets in a vacuumoffers the appealing possibility to investigate supercooled water—below the melting point but still a liquid—at temperatures far beyond the state of th
