We report on the coherent phonon spectroscopy of polymorphic MoTe2 single crystals using a femtosecond-pulsed laser to investigate relationship between structural phase transitions and photo-thermal effects induced by high-density excitation. Even when femtosecond pulsed was used, which generally induces fewer heat accumulation than case for CW laser, tellurium segregation observed in spectra w...

Abstract Due to their atomic-scale thickness, handling and processing of two-dimensional (2D) materials often require multistep techniques whose complexity hampers large-scale integration in modern device applications. Here we demonstrate that the laser-induced forward transfer (LIFT) method can achieve one-step, nondestructive printing prototypical 2D material MoS 2 . By selecting optimal LIFT...

Context: It has been proposed that H$_2$ near-infrared lines may be excited by cosmic rays and allow for a determination of the cosmic-ray ionization rate in dense gas. One-dimensional models show measuring both gas column density line intensity enables constraint on as well spectral slope low-energy protons interstellar medium (ISM). Aims: We aim to investigate impact certain assumptions regar...

Plutonium dioxide (PuO2) is an important compound used in nuclear fuel, irradiation targets, and heat sources. As such, improved understanding of its structural spectroscopic properties has numerous applications. Alpha particle-induced damage a PuO2 crystal lattice modifies several Raman spectrum, including band intensities, positions, widths. The decay also induces growth new bands creates ele...
