Summary: Doping silicon with phosphorus and introducing localized magnetic moments results in a correlated electronic ground state known as Kondo condensation. By conducting electrical transport and density-of-states spectroscopy measurements, we detect the Kondo effect and observe an unusual pseudogap in the resistivity and density of states of the highly P-doped silicon metal. These observations provide evidence of Kondo condensation followed by a transition to a disordered Fermi liquid phase.

Summary: The development of future optoelectronic materials relies on the high-performance p-type materials with optical transparency. Epitaxial growth of gamma-CuI on single crystalline Si(111) using a room-temperature electrochemical method demonstrates high in-plane and out-of-plane order. The deposition mechanism involves nucleating CuI seed crystals on n-Si(111) and simultaneous oxidation of Si to form SiOx, resulting in the lateral overgrowth of CuI seeds into a continuous film.

Summary: Researchers have achieved a deep UV transparent and highly conductive thin film material. The film has high transparency in the visible light to deep UV wavelength range and low work-function. The high conductivity is attributed to the delocalized conduction band derived from Ga 4s orbitals. Additionally, adding silicon improves the film's mobility. This material shows promise for applications in high-power electronics and deep UV and organic-based optoelectronic devices.

Summary: A transparent electrode made of gold nanoparticles was created using chemical reduction. It was compared with a commonly used gold-film-coated electrode to investigate its potential as a counter-electrode in dye-sensitized solar cells. The study found that the gold nanoparticles electrode achieved 80% average visible transmittance and showed promise for use in DSSCs.

Summary: Despite efforts to find room temperature ferromagnetic 2D materials, only a few have been synthesized. A recent study confirmed room temperature ferromagnetism in a multilayer structure. However, calculations showed an antiferromagnetic ground state in the monolayer and bilayer systems. Further investigation revealed that hydrogen-induced ferromagnetism was possible. The resulting systems showed a ferromagnetic ground state and optically transparent behavior.

Summary: We propose an acceleration-sensing protocol based on an array of optically levitated microspheres. The microspheres are suspended in a driven optical cavity using holographic optical tweezers. By properly positioning the microspheres relative to the cavity, the motion of the microsphere array is coupled to the cavity mode. The acceleration acting on the microsphere array is encoded onto the intracavity photons, which can be directly detected at the output of the cavity. The use of an array of optically levitated microspheres improves sensitivity by a factor of √N compared to traditional single-microsphere measurement schemes.

Summary: Anatase TiO2 nanocrystals were prepared via a simple non-aqueous sol-gel route and showed excellent photoreactivity in aqueous media, which could be further enhanced by doping with iron and UV-light pre-treatment. The effect of surface ligands on photoreactivity was thoroughly investigated, revealing a decrease in photocurrent and quantum efficiency upon doping due to the introduction of shallow defect states in thin-film electrodes made from the same TiO2 nanocrystals.

Summary: Solar-powered photochemical water splitting using suspensions of SrTiO3-based photocatalyst nanoparticles has attracted attention due to its potential for green hydrogen production. Doping the SrTiO3 nanoparticles with 1% Rh introduces midgap acceptor states, reducing the free electron concentration and built-in potentials, as well as acting as recombination centers, decreasing the photocarrier lifetime and maximum achievable EQY. The absence of built-in electric fields within Rh-doped SrTiO3 nanoparticles suggests the possibility of achieving moderate electron-hole separation through a difference in mobility.

Summary: A method for fabricating thin films for electrostatic deposition of colloidal silver nanoplates was developed in this study. The deposition rate and surface coverage of nanoplates were found to be dependent on factors such as molar concentration and surface zeta potential. A simple model and Monte Carlo simulation were used to understand the deposition kinetics based on the principle of effective exclusion radius.

Summary: We present a transparent and flexible polyimide (PI)-doped single-layer (PSL) phototransistor for visible light detection. By co-sputtering amorphous indium-gallium-zinc oxide (IGZO) and PI targets, the PSL is deposited on a SiO2 gate insulator, serving as both a channel layer and a visible-light absorption layer. The PI doping leads to improved optoelectronic characteristics, including higher photoresponsivity, photosensitivity, and specific detectivity, attributed to the induced subgap states. A flexible PSL phototransistor is also fabricated, demonstrating stable optoelectronic characteristics even after 10,000 bending tests.

Summary: Our study on energy transfer mechanisms in PF-RuOs complexed with Ru and Os polypyridyl complexes revealed that pendant flexibility plays a crucial role in enhancing the sensitization of Os traps, allowing a higher percentage of excited states to participate in energy transfer compared to static pendants. The computational experiments demonstrated that the flexibility of side chains enables the excited state to spread across a larger domain of complexes, enhancing the efficiency of energy transfer processes.
