英文摘要	The pyroelectric properties of (1-x)pb(mg1/3nb2/3)o-3-xpbtio(3) (pmn-xpt) single crystals have been investigated over a broad composition range of 0.13 <= x <= 0.40. the best pyroelectric performances are achieved in < 111 >-oriented pmn-0.26pt single crystal. at room temperature, the figures of merit for voltage responsivity and detectivity reach up to 0.11 m(2)/c and 15.3x10(-5) pa-1/2, respectively. these properties are superior to those of conventional pyroelectric ceramics that have been widely used in device applications. pmn-0.26pt single crystal also possesses a relative high curie temperature (similar to 120 degrees c) and a low thermal diffusivity (similar to 4.4x10(-7) m(2)/s). furthermore, the pyroelectric properties of pmn-xpt (x >= 0.26) single crystals are weak dependent on temperature and nearly independent of frequency in the experimental temperature range of 20-55 degrees c and frequency range of 50-10 000 hz. the superior pyroelectric performances of the single crystal make it a promising candidate for high-performance uncooled infrared detectors and thermal imagers.
