Electron Thermalization and Relaxation in Laser-Heated Nickel by Few-Femtosecond Core-Level Transient Absorption Spectroscopy
Hung-Tzu Chang, Alexander Guggenmos, Scott K. Cushing +9
Direct measurements of photoexcited carrier dynamics in nickel are made using few-femtosecond extreme ultraviolet (XUV) transient absorption spectroscopy at the nickel M ed…
Ultrafast demagnetization dynamics in Ni: role of electron correlations
Shree Ram Acharya, Volodymyr Turkowski, Guo-ping Zhang Talat S. Rahman
Experimental observations of the ultrafast (less than 50 fs) demagnetization of Ni have so far defied theoretical explanations particularly since its spin-flipping time is much les…
Sub-monolayer structures of Ag overlayers on Ge(111): experimental observations and first-principles study
Shree Ram Acharya, Cory H. Mullet, Jason A. Giacomo +3
We present a joint experimental and theoretical determination of structures of Ag adatoms on the Ge(111) surface using low energy electron diffraction, low energy electron microsco…
On the validity of the Arrhenius picture in two-dimensional submonolayer growth
Joseba Alberdi-Rodriguez, Shree Ram Acharya, Talat S. Rahman +2
For surface-mediated processes, such as on-surface synthesis, epitaxial growth and heterogeneous catalysis, a constant slope in the Arrhenius diagram of the corresponding rate of i…
Prediction of activation energy barrier of island diffusion processes using data-driven approaches
Shree Ram Acharya, Talat S. Rahman
We present models for prediction of activation energy barrier of diffusion process of adatom (1-4) islands obtained by using data-driven techniques. A set of easily accessible feat…
