Abstract This study explores defect engineering in 2D materials using ion beam irradiation to modify the electrical and optical properties with potential in advancing quantum electronics and photonics. Helium and neon ions ranging from 5 to 7.5 keV a

Semiconductor nanowires are promising candidates for the realization of novel transistor concepts. Here, the authors demonstrate that electron mobility in strained coaxial nanowire heterostructures can be higher than in the corresponding bulk crystal

Resonance Raman scattering, which probes electrons, phonons and their interplay in crystals, is extensively used in two-dimensional materials. Here we investigate Raman modes in MoSe$_2$ at different laser excitation energies from 2.33 eV down to the

Here we report a pronounced redshift of the trion resonance in MoSe 2 monolayer induced by picosecond THz pulses. The kinetic energy gained by hot carriers due to absorption of THz radiation is transferred during the formation of the trion, leading t

We investigate Raman scattering of MoSe 2 crystals with excitation energies in the visible and in the infrared (from 1.16 eV to 2.33 eV). We show that, despite the lower scattering efficiency at longer wavelengths, it is possible to measure also MoSe
