一、前言热电探测器是近十多年来发展起来的一种非常重要的红外器件。这类探测器具有一系列众所周知的优异性能:可在室温使用,不需致冷,响应光谱范围宽,制造工艺简单,价格低廉,应用广泛,材料来源渠道多等等。因而,热电探测器一问世,便受到世界各国的重视。从而,在热电材料、器件工艺和应用领域等方面的研究,得到了迅速的发展。 I. Introduction Thermoelectric detectors are a very important infrared device that has developed over the past decade or so. This detector has a series of well-known excellent performance: can be used at room temperature, without refrigeration, wide response spectrum, manufacturing process is simple, low cost, wide range of applications, materials, sources and more. Therefore, the advent of pyroelectric detectors, it will be the attention of all countries in the world. Thus, the thermoelectric materials, device technology and application areas such as research, has been rapid development.
