(GST)层的厚度、ITO层的厚度、GST层的晶态与非晶态的变化。结果表明:对于反射型器件,ITO层的厚度对器件的反射光谱影响较大,可以通过改变ITO层的厚度达到改变器件颜色的效果;GST层的厚度为12 nm时,GST的晶态与非晶态的变化使器件有最好的颜色对比度且消耗较低的电功率。对于透射型器件,通过使用超薄的GST薄膜,器件的透明度可以保持很高,器件的透明度在GST的厚度超过几纳米后迅速下降。

(GST) thin films were studied by simulation. It was showed how such a system
when combined with a transparent electrode such as indium tin oxide (ITO)
could be used as displays on reflective and transparent substrates both on rigid and flexible surfaces. To understand the relationship between the thickness of ITO and GST layers and the overall optical properties of the stack
the reflectivity spectrum of the stack was systematically computed while the thickness of each layer was gradually increased. For the reflection type device
the thickness of ITO has great influence on the reflection spectrum of the device
and the color of the device can be changed by changing the thickness of ITO. When the thickness of GST is 12 nm
the color contrast of the device is the best which is achieved by changing the phase of GST between amorphous and crystalline
and the power consumption is low. For the transmission type device
the transparency of the device can be very high by using ultra-thin GST film
but the transparency declines rapidly when the thickness of GST is more than a few nanometers.
