20211001· The QCM mass gains during APTES exposure at 200 °C are in the range of 46–54 ng cm −2 for all three oxides, but at 100 °C the QCM mass gain during APTES exposure on Al 2 O 3 ( ng cm −2) is significantly higher than on ZnO ( ng cm −2) and TiO 2 ( ng cm −2). ...


Metal/Nitrides, Metal Oxides | ald807

Mass change during an ALD cycle consisted of a CpCo(CO)2 pulse, a purge, a O3/O2 pulse, and a purge. The m1 is the mass change during a cobalt precursor pulse and the m0 is the mass increment after a complete ALD cycle. Exposure of CpCo(CO)2 and O3/O2 were 2 106 and 5 108 L, respectively.

Development of Piezoelectric MEMS Devices Using Quartz Crystal and Pb(Zr,Ti)O3 Thin Films. In this study, the development of piezoelectric MEMS based on quartz crystal and Pb(Zr,Ti)O 3 (PZT) thin film is presented. Quartz crystal microbalance (QCM) resonators were fabricated by MEMS technology. For detection of gas at room temperature with rapid response and recovery, the QCM resonators were ...


In situ investigations of the metal/atmophere interface

The roles of O3 and NO2 in the SO2induced atmosphericcorrosion of copper was also investigated. O3 was found to havea twofold effect, resulting in the oxidation of the coppersulfite species to copper sulfate and the enhancement of Cu2Oformation. NO2 promoted the oxidation of copper sulfitespecies, though less efficiently than O3, and reduced Cu2Oformation. In addition, copper nitrate ...

LowTemperature Al2O3 Atomic Layer Deposition

the QCM for monitoring ALD has been presented in a previous Al 2O 3 ALD films were deposited on PET bottles at 58 °C. To accommodate the 510mL PET bottles, the standard reactor flow tube was replaced with a larger 10cm diameter tube as shown in Figure 1. This tube consisted of the bottom halves of two vacuum traps joined by an Oring and a clamp. The bottles were suspended in ...

Modeled afternoon plumes reached a maximum O3 mixing ratio of 140 ± 50 ppbv (average ± standard deviation) within 20 ± 10 min of emission compared to 76 ± 12 ppbv in 60 ± 30 min in evening plumes. Afternoon and evening maximum O3 isopleths indicate that plumes were near their peak in NOx efficiency. A radical budget describes the NOx volatile organic compound (VOC) sensitivities of ...
