WebThe long-term precise high-temperature measurement of thin-film thermocouples (TFTCs) has attracted attention due to the capability of instantaneous temperature detection. However, related technologies have seen slow development, and there is no one standard TFTC yet. Here, we focus on a new strategy of redu Web2 days ago · The topographical surface of Ir(ppy) 3 was examined using an atomic force microscope (AFM; manufacturer: Veco-D3000).The current and voltage delivered to the AFM tube were 30 mA and 40 kV, respectively. The scanned area of the film was 5μm × 5μm, and the scanning rate was 1 Hz. The crystallite structure of the thin film is determined using a …
WebJun 1, 2016 · Iridium has been deposited on a 29 nm thick SrTiO 3 film on Si at 920 °C for a first test. Which corresponds to the temperature of iridium deposition on bulk SrTiO 3. However, at this temperature, a non-epitaxial film with voids was observed by FE-SEM ( Fig. 4 ). The surface also presented crystals with different shapes. WebOct 29, 2024 · The present invention relates to a film quality improving agent, a thin film formation method using same, and a semiconductor substrate manufactured therefrom, whereby, by using the film quality improving agent, having a predetermined structure, in a thin film deposition process, side reactions are inhibited, thin film growth rate is …
WebAtomic layer deposition (ALD) was used to prepare thin-film mixtures of iridium and platinum. By controlling the ratio between the iridium (III) acetylacetonate/oxygen cycles for Ir ALD and the (trimethyl)methylcyclopentadienyl platinum (IV)/oxygen cycles for Pt ALD, the Ir/Pt ratio in the films could be controlled precisely. WebFeb 25, 2011 · Thin Ir films were deposited onto clean (111) Si surfaces. The films were analysed by Rutherford backscattering and transmission electron microscopy and were shown to be continuous for film thicknesses as small as 0.5nm. The films contained internal stress as deposited and coiled up when the substrate was removed chemically.
WebIridium oxide thin-films can be deposited through reactive sputtering whether the target is dc-powered [4] or rf-powered [2] in a plasma environment. Iridium oxide species were pulsed dc-sputtered as reported in this work. Pulsed power as opposed to dc-power prevents the formation of arcs [4]. DC-sputtering of dielectrics causes the
