Vo _ 2 is a typical thermochromic material . with the increase of temperature , the semiconductor - to - metal transition will occur at 68 c ; with the abrupt change of vo _ 2 crystal structure , electrical resistance and optical index of refraction transmissivity and reflectivity will change , which results in great application potentials in many fields
Vo2是一种相变型金属氧化物,随温度的升高,在相变温度( tc = 68 )发生从低温单斜结构向高温四方金红石结构的转变,同时,伴随着电阻率和红外光透过率的突变。
Substrates so as to give a microwave index close to the optical index , thus the high bandwidth and high switching speed of the boa device can been gained ; combining the characteristics of the boa device , we proposed a traveling - wave electrode boa - type device of 3db bandwidth greater than 20ghz . on the basis of the theoretical analysis , design and the study on the fabricating technique , we have made the fabrication of the chip using the self - adjusted technics
在前面器件理论分析、设计和工艺研究的基础上，我们完成了gaas gaaias双异质结boa波导型光开关集成光学芯片的制作，单个器件的大小可以控制在15xlnd以内，制作后的器件形状较理想c但目前由于条件所限，我们目前仅测量了器件的ai gaasschottky特性和器件初步效应。
