Radiation of X-rays using Uniazially Polarized LiNbO3 Single Crystal
The effect of emitted electron from carbon nanotube (CNT), of which shape is easy to emit electrons, on the X-ray intensity radiated using a polarized pyroelectric single crystal of LiNbO3 was investigated at an air pressure of approximately 7×10-3 Pa. The negatively charged surface of the crystal was placed opposite an oxygen-free copper foil target, its temperature was altered, and the electric field was generated. When the crystal is deteriorated by self polarization reversal and can not generate an electric field with high intensity, the X-ray intensity radiated using this crystal drastically increased with increasing the area of CNT. Moreover, X-ray radiation could be stabilized using CNT. For the crystal without deterioration, it was found that the X-ray intensity decreased for small area of CNT and increased again with increasing the pasted area.
