I need to know about the material to use as a medium or spacer between GaAlAs/GaAlAs layers and for GaAlAs/GaAs heterostructure. How would I make the selection of the spacer material for these type of bilayer system? If any other suggestion you need to give then please tell me.
Dear Sharad,
welcome,
What is the function of the spacer layer in the intended structure and how is the layer stack required? The choice of the material depends on its fucntion in the structure. Do you want to make multijunction tandem solar cell from three five compounds?
Best wishes
With respect and thanks to Abdelhalim Zekry and others to respond here. Dr. Zekry, you think right, in multijunction I am trying to study the effect of spacer/medium. My system is exactly as solar cell materials are used, and your example tandem solar cell which resemble as my system.
