Bi₂Te₃ Thin Films Deposited by the Combination of Bi and Te Plasmas in a PLD Process. [PDF]

Micromachines (Basel), 2023
Bismuth telluride thin films were grown by pulsed laser deposition by implementing a novel method that combines both Te and Bi plasmas resulting from the laser ablation of individual Bi and Te targets. Furthermore, the mean kinetic ion energy and density

New Reflections on Gravitational Duality

Frontiers in Physics, 2018
In general terms duality consists of two descriptions of one physical system by using degrees of freedom of different nature. There are different kinds of dualities and they have been extremely useful to uncover the underlying strong coupling dynamics of
