Ultranarrow Photoluminescence from Individual Graphene Nanoribbons Showing Single-Photon Emission

Bernd K. Sturdza, Amit Pawbake, C. Faugeras, Wenhui Niu et autres

Graphene nanoribbons (GNRs) combine the remarkable optical and electronic properties of graphene with the presence of a tunable band gap, making them promising for optoelectronic applications. Here, we investigate the excitonic properties of individual cove-edge GNRs through microphotoluminescence (micro-PL) spectroscopy. We observe …

Inverse design of terahertz amplitude modulator using tandem deep neural networks

Tae-In Jeong, Eunji Choi, R. D. Taylor, Seungchul Kim

The terahertz (THz) frequency range has emerged as a promising spectral window for broad applications, including next-generation wireless communication, high-resolution imaging, and ultrafast spectroscopy. Among the essential components in these systems, amplitude modulators with high quality (Q) factors can provide sharp, selective …

Using graph neural networks to reconstruct charged pion showers in the CMS High Granularity Calorimeter

Muhammad Aamir, G. Adamov, T. Adams, C. Adloff et autres

Abstract A novel method to reconstruct the energy of hadronic showers in the CMS High Granularity Calorimeter (HGCAL) is presented. The HGCAL is a sampling calorimeter with very fine transverse and longitudinal granularity. The active media are silicon sensors and scintillator tiles …

Mechanisms for pressure-induced crystal-crystal transition, amorphization, and devitrification of SnI4

Hanyu Liu, John S. Tse, Michael Y. Hu, Wenli Bi et autres

The pressure-induced amorphization and subsequent recrystallization of SnI4 have been investigated using first principles molecular dynamics calculations together with high-pressure (119)Sn nuclear resonant inelastic x-ray scattering measurements. Above ∼8 GPa, we observe a transformation from an ambient crystalline phase to an intermediate …

Evidence for direct impact damage in metamict titanite CaTiSiO5

Ekhard K. H. Salje, R. D. Taylor, D. J. Safarik, J. C. Lashley et autres

We have measured the dose dependence of the degree of amorphization of titanite, CaTiSiO(5). Titanite is an often metamict mineral which has been considered as a matrix for the encapsulation of radiogenic waste, such as Pu. The amorphous fraction p of geologically …

Intricate relationship between pressure-induced electronic and structural transformations in FeCr 2 S 4

Y. Amiel, G. Kh. Rozenberg, Noaz Nissim, A. P. Milner et autres

Electrical-transport, magnetic and structural properties of the ferrimagnetic semiconductor FeCr${}_{2}$S${}_{4}$ (${T}_{\mathrm{N}}$ $=$ 170 K) have been studied by electrical resistance, $R$($P$, $T$), ${}^{57}$Fe M\"ossbauer spectroscopy (MS), and synchrotron x-ray diffraction to 20 GPa using diamond anvil cells. It was found that the …
