The excess of surface dangling bonds makes the formation of free-standing two-dimensional
(2D) metals unstable and hence difficult to achieve. To date, only a few reports have …

Recent studies of the surface dynamics of Al (001) and Cu (111) based on density functional
perturbation theory have substantiated the existence of subsurface optical phonon …

The cleaning procedure consists of two-step-flashing:(i) cycles of low power flashes (T∼
1200K) at an oxygen partial pressure of [Formula: see text], to remove the carbon from the …

We report the first observation of high wave vector magnon excitations in a ferromagnetic
monolayer. Using spin-polarized electron energy loss spectroscopy, we observed the …

Surface enhanced Raman scattering (SERS) is generally and widely used to enhance the
vibrational fingerprint of molecules located at the vicinity of noble metal nanoparticles. In this …

Background The Mössbauer effect has been detected for a total of nearly 90 γ-ray transitions
in 72 isotopes of 42 different elements. Figure 2 shows the Periodic Table of the elements in …

Phonons play a crucial role in thermalization and non-radiative recombination losses in
semiconductors, impacting the power conversion efficiency of solar cells. To shed light on …

An in-plane spin-reorientation transition occurring during the growth of epitaxial Fe films on
W (110) was studied in situ by using the nuclear resonant scattering of synchrotron radiation …

The structure, magnetic properties, and lattice dynamics of ordered Fe–Pt alloys with three
stoichiometric compositions, Fe 3 Pt, FePt and FePt 3, have been investigated using the …

Reducing the size of a superconductor below its characteristic length scales can either
enhance or suppress its critical temperature (T c). Depending on the bulk value of the …
