The electronic structure of hafnene grown on the Ir(111) substrate has been studied using angle-resolved photoemission spectroscopy (ARPES). The observed band structure of hafnene near the Fermi level is a parabolic dispersive electron pocket centered at the Γ point of the Brillouin zone, demonstrating the existence of two-dimensional (2D) electron gas in hafnene grown on an Ir(111) substrate.

The F anion leaching facilitates surface reconstruction and induces a space-charge effect on the p–n junction interface, which not only promotes the absorption of intermediates species and charge-transfer process during catalysis, but also leads to a strong interaction of the p–n junction interface to stabilize the materials.

The incorporation of hydrogen in VO2 nanosheets gave rise to the balanced O confinement sites in VO2, leading to the stabilized adsorption configuration and increased binding strength of UO22+ on Hx-VO2 nanosheets. Thus the hydroxylated surface of Hx-VO2 nanosheets contributed to the remarkable catalytic activity toward U(VI).

Our study shows that highly uniform InGaAs arrays with tunable optical properties can be grown by selective area epitaxy. The effective Ga content in the nanowires can be changed by controlling the growth conditions, enabling the precise tuning of their optical emission over a range of 0.6 eV.
