Two novel phases of germa-graphene: Prediction, electronic and transport applications

Electric Field‐Induced Phase Transition on HPX6 (X = C, Si, Ge, Sn) Monolayers

“…The calculated values of E c have been presented in Table 1, and we can conclude that the structures are less stable for heavier elements. The values are comparable to that obtained for graphene [ 55 ] and other stable carbon allotropes like phagraphene, [ 56 ] germagraphene, [ 57 ] and reveal that hydrogenated PX 6 monolayers are stable structure.…”

A First-Principle Study of Two-Dimensional Boron Nitride Polymorph with Tunable Magnetism

“…Due to its special electronic and magnetic characteristics, graphene is considered to be a revolutionary material for multiple facilities, such as high-speed electronic devices, thermal and conductivity-enhancing composite materials, sensors, RF logic devices, transparent electrodes, etc. [1][2][3][4][5][6]. In recent years, novel theoretical two-dimensional materials based on first-principles calculations have shown many interesting physical and chemical properties [7][8][9][10][11][12].…”

Cost Effective Photothermal Materials Selection for Direct Solar-Driven Evaporation

“…These variations are attributed to the presence of surface groups and π-conjugated structures in their carbon cores . Notably, graphene exhibits exceptional light absorption capabilities, absorbing 2.3% of light across a wide spectrum due to its unique electronic structure known as “Dirac cones.” , For comparison, plasmonic localized heating occurs when these nanomaterials absorb light, leading to the conversion of light energy into heat via plasmonic oscillations of free electrons. , Similarly, in semiconductor materials, nonradiative relaxation takes place as absorbed photons generate electron–hole pairs, with the excess energy dissipating as heat through nonradiative pathways instead of being emitted as light . In contrast, thermal vibration in molecules, observed in carbonaceous and organic polymer materials, is triggered by the absorption of light energy, prompting the atoms within the molecules to vibrate and produce heat due to frictional forces .…”
