Organic field-effect transistors (FETs) are considered to be used as high-end electronics and low-end ones. In the low-end electronics such as radio-frequency identification tags and smart-cards the devices should be battery-powered and then need to operate at a few volts. Majority of the organic FETs reported to date, however, can only operate well at a voltage as high as ∼100V. Three kinds of approaches...
We have investigated on the synthesis of SrTiO 3 nanoparticles whose bulk exhibits dielectric constant of 300, and their colloidal dispersion. As a result, we successfully synthesized SrTiO 3 nanoparticles with an average diameter of 134–485nm measured by a scanning electron microscopic observation. The SrTiO 3 nanoparticles with a negative charge (ζ=−25 to −31mV) can be dispersed...
