Summary: In this study, we prepared indium tin oxide (ITO) films on a glass substrate using facing-target sputtering and investigated the effect of heating treatment on the properties of the films. Additionally, we fabricated perovskite solar cells (PSCs) with ITO films prepared at different oxygen flows during the sputtering process and studied their energy conversion properties.

Summary: This study investigates the impact of oxygen flow rates on the performance of ITO/ITO(O-2)/TiN structured RRAM. It was found that devices with lower oxygen flow rates exhibit better electrical characteristics and reliability. Experimental results suggest the use of Schottky emission conduction mechanism for high-resistance state and Ohmic conduction mechanism for low-resistance state.

Summary: In this study, nanostructured ITO thin films were prepared using ion beam sputtering and oblique angle deposition techniques, and the effects of different experimental conditions on the surface texture of the films were investigated. The results demonstrate that the texture engineering of the films can be achieved by controlling the atomic mobility and deposition angle under specific experimental conditions.

Summary: During the formation of transparent conductive oxide (TCO) electrodes by sputtering, the organic layer surface is damaged, affecting the performance of transparent organic devices. High-energy particles formed during the sputtering process are identified as the main cause of this damage. By studying the energy distribution of these particles, it was found that changing the O2 content in the sputtering gas can alter the number of positively charged particles without degrading the current-voltage characteristics of the organic devices.

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: Amorphous aluminum-doped indium tin oxide (ITO) thin films were manufactured by co-sputtering ITO and Al2O3 targets onto glass substrates, with the oxygen flow rate and heat treatment temperature affecting the electrical, optical and structural properties. Optimally sputtered films showed improved conductivity and transmittance while hindering crystallization, with a volume resistivity of 713 mu omega cm, mobility of 30.8 cm(2)/V center dot s, carrier concentration of 2.9 x 10(20) cm(-3) and over 90% transmittance in the visible range.

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: This study investigated the impact of H2O partial pressure on the properties of indium tin oxide (ITO) films and the performance of heterojunction (HJT) solar cells. As the H2O partial pressure increased, the resistivity of ITO films increased and the effective total transmittance slightly improved. However, HJT solar cells with ITO films deposited at high H2O partial pressure had lower efficiency due to the degradation of fill factor (FF). The maximum efficiency of 25.30% was achieved at low H2O partial pressure. Additionally, the performance of HJT solar cells was tracked under a nitrogen environment without illumination, and it was found that the high efficiency obtained at low H2O partial pressure had larger degradation, mainly derived from FF degradation.

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.
