Optical Response of Highly Granular Ybacuo Films Prepared by Non-vacddm Aerosol Deposition
نویسنده
چکیده
Highly granular YBaCuO films on SrTlO, substrates wlth T,,,-90K and J,>lO' A/cm2 were prepared by non-vacuum aerosol deposition. The optical response for these films was investigated on a 10 x 10 pm2 mlcrobrldge. Besides a bolometrlc response around the transition temperature, a sharp response peak was observed at low temperature and high bias current using a He-Ne laser (0.63pm wavelength) lllwnlnatlon. This response was caused by a junction behavlour due to the presence of many boundary-type weak links in our mlcrobridge.

متن کاملAerosol Deposition on Transparent Electro-Optic Films for Optical Modulators
Complex thin oxide films with electro-optic (EO) properties are promising for use in advanced optical devices because of their large EO effect. We developed a method of aerosol deposition (AD) for fabricating EO films. The mechanism for AD is based on the solidification by impact of submicron particles onto a substrate. Since particles in AD films preserve their crystalline structure during the...
