Hybrid polymer solar cells with well ordered TiO2 nanostructures have attracted attention as a promising new photovoltaic device. This new device structure is to improve the power conversion efficiency of a solar cell by enhancing light absorption, charge injection, and carrier transport. In this study, sol-gel and atomic layer deposition (ALD) methods were used for the fabrication of various TiO2...
Electrical properties of nano size devices were directly measured by TEM. Real time observation of phase transition behavior in PRAM revealed that the volume of the crystalline phase is the main factor in determining cell resistance. In the transistor device, we have identified the doping type and area by measuring the I-V curve at the individual nano contact on the specimen. The evolution of the...
The primary purpose of this work was to investigate the relative heat removal effectiveness of various thermal interface and buried oxide materials as they would be used in actual conditions. The thermoreflectance thermography approach was used to measure, non-invasively and with submicron spatial resolution, the surface temperature fields of two types of thermal test devices: (i) Delphi thermal test...
To investigate the sequentially plasma-activated bonding (SPAB) mechanism of silicon/silicon wafers, the surface hydrophilicity, and the interface voids, nanostructures and chemical compositions that control the bonding quality, such as bonding strength, have been observed. Although the sequentially plasma-activated surfaces are hydrophilic, the SPAB mechanism is not identical to the hydrophilic bonding...
