“…It has been suggested that this mechanism is more important for screening polar surfaces of smaller bandgap oxides such as SrTiO 3 (bandgap of 3.0 eV [39]) compared to wide bandgap insulators such as MgO (7.7 eV [41]). On this scale, LiNbO 3 with a bandgap of 3.75 eV [13] more closely resembles SrTiO 3 .…”

“…Piezoelectric microcantilever sensor ͑PEMS͒ consisting of a highly piezoelectric layer such as lead zirconate titanate 1 ͑PZT͒ or lead magnesium niobate-lead titanate 2,3 ͑PbMg 1/3 Nb 2/3 O 3 ͒ 0.63 -͑PbTiO 3 ͒ 0.37 ͑PMN-PT͒ bonded to a nonpiezoelectric layer such as tin is a new type of mass sensor that uses electrical means for detection and can be miniaturized for better mass detection sensitivity. 4 Most of the electrical insulation coating of miniaturized devices such as piezoelectric/piezoresistive microcantilever sensors and surface acoustic wave ͑SAW͒ sensors employed ceramic 5,6 or polymeric 7,8 coating deposited by high-vacuum deposition techniques. Other polymeric insulation coatings such as polyimides 9,10 and benzocyclobutene 11 ͑BCB͒ can be deposited by wet solution methods, and to be effective they require a thickness of tens of microns, which is too thick for PEMS applications.…”

We have examined coating (PbMg(13)Nb(23)O(3))(0.63)-(PbTiO(3))(0.37) (PMN-PT)/tin and lead zirconate titanate (PZT)/glass piezoelectric microcantilever sensor (PEMS) with 3-mercaptopropyl-trimethoxysilane (MPS) by a simple solution method to electrically insulate the PEMS for in-water applications. In contrast to earlier methytrimethoxysilane insulation coating, the MPS coating also facilitated receptor immobilization on the sensor surface via bonding of its sulhydryl group to a bifunctional linker, sulfosuccinimidyl-4-(N-maleimidomethyl)cyclohexane-1-carboxylate. We showed that a MPS coating of 21 nm in thickness is sufficient to electrically insulate and provide immobilization surface to the PEMS for in-liquid electrical self-excitation and self-sensing. The in-phosphate buffered saline solution resonance spectra were stable with Q values ranging from 41 to 55. The mass detection sensitivities were determined to be 5x10(-11) and 8x10(-12) gHz for the MPS-insulated PZT-glass and PMN-PT/tin PEMSs, respectively.

“…The organic-inorganic hybrid coatings can improve mechanical, physical characteristics together with durability and used particularly for improvement of resistance against electric insulation, oxidation and corrosion. [1][2][3][4] Sol-gel method is a chemical synthesis method employed in inorganic polymerization reaction for preparation of inorganic materials as a raw material for glass and ceramics. In the past 10 years, organic-inorganic hybrid nano composites prepared by the sol-gel method have been used in the areas of ceramics, polymer chemistry, organic and inorganic chemistry, and physics.…”

Sol-gel binder was prepared by hydrolysis and condensation reaction using boehmite sol and methyltrimethoxysilane as a function of aging-time. The coating slurry was composed of a plate-shape alumina in the sol-gel binder for the EPD process, in which particles dispersed in the slurry were deposited on the electrode under an electric field due to the surface charge. We studied the effects of three parameters: the content of boehmite, the aging time, and the applied voltage, on the physical, thermal, and electrical properties of the hybrid composite films by EPD. The amount of boehmite was 10 ~ 20 wt% and the aging time was 0.5 7 2 , with a fixed amount of plate-shape alumina of 10 wt%. The condition of applied voltage was 5 ~ 30 V with a distance of 2 cm between the electrode during the EPD process. We confirmed that a structure of hybrid composite films of well-ordered plate alumina was deposited on the substrate when the film was prepared using a sol-gel binder composed of 15 wt% boehmite with 1 hr aging time and EPD at 10 V. The process shows a weight loss of 7% at 500 o C in TGA and a breakdown voltage of 8 kV at 87 µm.
