We review the current understanding of charge carriers in model hematite photoanodes at
different stages. The origin of charge carriers is discussed based on the electronic structure …

The dielectric permittivity of a material encapsulates the essential physics of light-matter
interaction into the material's local response to optical excitation. Photo-induced modulation …

Optical fields interacting with solids excite single particle quantum transitions and elicit
collective screening responses that define their penetration, absorption, and reflection. The …

Many linked processes occur concurrently in strongly excited semiconductors, such as
interband and intraband absorption, scattering of electrons and holes by the heated lattice …

The light-mediated interaction of fermionic and bosonic excitations governs the
optoelectronic properties of condensed matter systems. In photoexcited semiconductors, the …

Zinc compounds and derivatives are gaining prominence as antibacterial agents capable of
generating oxidative stress and cell death in Gram-positive and Gram-negative bacteria by …

Loading metal cocatalyst on semiconductor nanoparticles is a general strategy to enhance
photocatalytic efficiency, while the consensus of selecting metal cocatalyst matching with …

In this work, the gas sensing properties of a single ZnO nanowire (NW) are investigated,
simultaneously in terms of photoluminescence (PL) and photocurrent (PC) response to NO2 …

The full transient dielectric-function (DF) tensor of ZnO after UV-laser excitation in the
spectral range 1.4–3.6 eV is obtained by measuring an m-plane-oriented ZnO thin film with …

Organic/inorganic hybrid systems offer great potential for novel solar cell design combining
the tunability of organic chromophore absorption properties with high charge carrier …
