A Subatmospheric Pressure Chemical Vapor Deposition (SAPCVD) system was implemented for SiO2 nanometric films deposition on silicon substrates. Tetraethoxysilane (TEOS) and ozone (O3) were used as precursors and they were mixed into the SAPCVD system at 590 Torr. The deposition temperatures ranged from 140 to 265 o C and the deposition time ranged from 1 to 15 min. The measured thicknesses from...

We have measured the fracture energy of lithiated silicon thin-film electrodes as a function of lithium concentration using a bending test. First, silicon thin-films on copper substrates were lithiated to various states of charge. Then, bending tests were performed by deforming the substrate to a pre-defined shape, producing a variation of the curvature along the length of the electrode. The be...

We proposed a structure of patterned TFT array films to prevent the macro‐cracks, which was implemented on foldable organic light‐emitting diode (OLED) display. The out‐bending tests demonstrated that protection can improve reliability. And limitation bending radius achieved 1.5 millimeter.

We review the theory of curvature elasticity of thin" fluid films starting with a phenomenological formalism motivated by microscopic, physical examples. The effects, of finite compressibility 'of the layer, exchange of molecules between the film and the solution, and the intrinsic bending stiffness of the film are taken into account· these degrees of freedom account for all the" important mole...

background: proper sleep is essential for the development of premature infants. infants, during hospitalization, might suffer from inappropriate postures and insufficient sleep hours. to compare the daily sleep quantities of premature infants in flexed (facilitated fetal tucking) posture and extended (free body) posture. this study is a randomized clinical trial which was conducted in neonatal ...

By combining x-ray excited Auger electron diffraction experiments and multiple scattering calculations we reveal a layer-resolved shift for the Mg KL23L23 Auger transition in MgO ultrathin films (4-6 Å) on Ag(001). This resolution is exploited to demonstrate the possibility of controlling Mg atom incorporation at the MgO/Ag(001) interface by exposing the MgO films to a Mg flux. A substantial re...

We have used dissipative particle dynamics to simulate amphiphilic monolayers on the interface between oil and water. An ultralow interfacial tension is imposed by means of Monte Carlo to resemble the amphiphilic films that separate oil and water regions in microemulsions. We calculate the bending modulus by analyzing the undulation spectrum. By varying the surfactant chain length and topology ...
