One promising method to pattern full color polymer Organic Light-Emitting Diode (OLED) displays is to print dye from a pre-patterned organic film onto a spin-cast polymer and then diffuse the dye into the film at room temperature in a solvent vapor environment. This method utilizes the well-known tendency for a polymer film to absorb solvent vapor, which depresses the glass transition temperatu...

Abstract (Pb,Nb)(Zr,Sn,Ti)O3 antiferroelectric (AFE) thin films have been fabricated on LaNiO3/Pt/Ti/SiO2/Si wafers using a sol–gel process. The electric field-induced antiferroelectric-to-ferroelectric (AFE–FE) phase transformation behaviour and its dependence on the temperature were examined by investigating the dielectric constant and dielectric loss versus temperature and electrical field. ...

In order to substantially reduce the costs of present crystalline Si solar cells, the material consumption of highly pure Si in a typical solar cell structure should be reduced. Most of the crystalline Si material merely acts as a mechanical carrier for the solar cell device with most of the optical absorption taking place in the upper 30μm region. When special care is taken to maximize optical...

We propose a temperature sensor employing a ring oscillator composed of poly-Si thin-film transistors (TFTs). Particularly in this research, we compare temperature sensors using TFTs with lightlydoped drain structure (LDD TFTs) and TFTs with offset drain structure (offset TFTs). First, temperature dependences of transistor characteristics are compared between the LDD and offset TFTs. It is conf...

We report results from a computational study of film cooling from cylindrical holes inclined at 35 degrees with respect to a flat surface using Large Eddy Simulations (LES). The hole length is L/d = 3.5, distance between the holes is P/d = 3, boundary layer above the flat surface is turbulent with Reθ = 938, density ratio = 0.95, velocity ratio = 0.5. All pertinent components of geometry, namel...

in the present research, effects of modified atmosphere packaging (map) includingthree gas combinations and two packaging films (low density polyethylene (ldpe) andpolypropylene (pp)) on postharvest quality and storage-life of 'elberta' peach wereevaluated. the study was conducted as a factorial experiment based on crd(completely randomized design) with three replicates for 9 weeks. f...

In this paper, numerical simulations have been conducted to study the effects of key environmental and test conditions (air velocity, temperature, film thickness, and sample application time) on volatile organic compound (VOC) emissions from a "wet" coating material (wood stain). Simulation results indicate that air velocity and sample application time only significantly affect the emission pro...

This work applies the molecular dynamics simulation method to study a Lennard-Jones liquid thin film suspended in the vapor and to explore the film thickness effect on its stability. For the accurate estimation of local pressure distributions in the film, an improved method is proposed and used. Simulation results indicate that profiles of the local surface tension distribution vary widely with...
