We present a new method for the complete thermoelectric characterization and figure of merit calculation of single nanowires (NWs) using a combination of spatially resolved 米-Raman spectroscopy and electrical measurements. We apply the new method to Se-doped InSb NWs.

Rutile TiO2 nanorods (NRs) with different oxygen vacancies were prepared by using TiN as a precursor. Oxygen vacancies with suitable concentration could effectively promote charge separation and enhance the photocatalytic activity of TiO2. Overall, the photocatalytic activity followed the order: TiO2 < S-TiO2每x < B-TiO2每x < S-B-TiO2每x, corresponding to stoichiometric TiO2 NRs and TiO2 NRs with surface reduction, hydrothermal crystallization, and combination treatment.

We plot the measured phonon frequencies of the A g1, B2g, and A g2 modes of few-layer black phosphorus (BP) under uniaxial tensile strain along both the near-armchair and near-zigzag directions. The pronounced dependence of the strained phonon frequencies on crystal orientations can be ascribed to an anisotropic mechanical response to uniaxial strain in BP, as a result of its unique puckered crystal structure.
