Summary: Integrative neural interfaces combining neurophysiology, optogenetics, and neural imaging offer opportunities for studying neural circuits in the brain. The development of ultra-flexible, highly conductive and fully transparent microscale electrocorticogram (mu ECoG) electrode arrays with PEDOT:PSS-ITO-Ag-ITO assembly shows enhanced mechanical flexibility, robustness, and resilience to photon-induced artifacts. In vivo experiments demonstrate successful recording of light-evoked ECoG oscillations from the primary visual cortex (V1) of an anesthetized rat.

Summary: Strong single-cycle THz emission has been achieved from nonlinear plasmonic metasurfaces by exciting them with femtosecond laser pulses. The use of indium-tin-oxide (ITO) films with epsilon-near zero (ENZ) behavior in the excitation wavelength range has enhanced the nonlinear conversion. However, the THz conductivity of the ITO film reduces the radiation efficiency of the meta-atoms. To overcome this, the ITO layer around the plasmonic meta-atoms is etched, allowing the harnessing of enhanced localized fields while improving the THz radiation efficiency. This fabrication scheme presents important progress in expanding the applications of nonlinear plasmonic metasurface THz emitters.

Summary: A novel method of doping Aluminum (Al) into zinc oxide (ZnO) nanorods by a simple chemical dip process is evaluated in terms of its performance in random lasing. The ZnO nanorods were synthesized using chemical bath deposition (CBD) method at 96 degrees C for 3 h. The nanorods were then dipped in a fixed doping solution concentration, and the dip time was varied between 0 s and 80 s. Doping ZnO nanorods in aluminum nitrate nonahydrate solution for 40 s contributes to random lasing with the lowest threshold value of 12.48 mJ/cm2 and a spectral width of 2.12 nm.

Summary: Indium tin oxide thin films were deposited on aluminum nitride substrates by magnetron sputtering and annealed at different temperatures. The study investigated the structural, optical, electrical conductivity, and gas sensitivity of these films. The results showed the potential of developing gas sensors with low resistance and high sensitivity. The annealed films at 500 degrees C exhibited high sensitivity to gases, with short response and recovery times. The qualitative model proposed in the study explained the sensory effect of the films.

Summary: A simplified TADF-OLED without HIL and HTL was achieved by modifying the surface of ITO with a composite self-assembled monolayer. This method increased the work function of ITO, improved the quality of the emitting layer film, and facilitated hole injection.

Summary: Transparent thermoelectric materials have been integrated with sensing and energy harvesting devices, using atomic layer deposition (ALD) of aluminum doped zinc oxide (AZO) on grass-like alumina (GLA). The conformal nature of the ALD process enables the AZO growth to closely follow the topography of the GLA film, increasing the effective surface area and improving electrical conductivity and thermoelectric power.

Summary: This study numerically investigates the ultrafast dynamic switching of optical response using a tunable hyperbolic metamaterial (HMM) on a femtosecond time-scale. The results show that the HMM platform allows large and broad all-optical modulation of the effective permittivity and topology, with considerable tunability in extinction ratio and Purcell enhancement under different pump fluence. Additionally, all-optical control of coupling strength is achieved by depositing plasmonic resonators on the HMM platform.

Summary: The argon atmospheric pressure plasma treatment is used in combination with the conventional sol-gel dip-coating process to improve the electrical properties of ITO glass by increasing the thickness and reducing the sheet resistance of the ITO thin films. However, prolonging the plasma treatment time beyond 240 seconds can lead to an increase in sheet resistance due to the diffusion of oxygen into the bulk, reducing the level of oxygen vacancies.

Summary: This contribution investigates the impact of thermal stress on Cu(In,Ga)Se-2 (CIGSe) thin film photovoltaic devices, focusing on their tolerance to high temperatures for potential applications in tandem solar cells. Elemental interdiffusion and chemical reactions at the CIGSe/CdS interface under thermal stress lead to degraded power conversion efficiency in CdS-buffered CIGSe solar cells. The study compares the degradation mechanisms of CdS and GaOx buffered CIGSe solar cells and proposes a model to explain the observed behaviors.

Summary: Silicon heterojunction technology shows promising potential for solar cells, but the current loss related to the front and rear contacts remains a limiting factor. By using dielectric layers to reduce the thickness of the transparent conductive oxide (TCO), parasitic absorption and material consumption can be diminished, but resistive losses also increase. Experimental bifacial cells with 20 nm TCO perform similarly to reference cells with 75 nm, and a screen printing metallization method enhances the current density without compromising resistive losses. This approach has resulted in a certified champion cell with an efficiency of 24.6%.
