Hello to all:
I'm trying to think in the following interesting problem:
I have a system which are polycrystals (grains) of Bi2Te3 (actually this compound is a quaternary alloy of Bi, Te, Se and Sb). The grains ended coated with Carbon, in the form of Graphene Nanoplatelets: a stack of several (or could be many) Graphene single Layers.
Does anyone know, have experience or have literature references about the following questions:
1. How an increment in temperature will affect the Chemical Stability of the Bi2Te3-alloy ? for two scenarios:
i. A normal day-to-day working temperature between 10 °C - 37 °C
ii. Or in the scenario reaching the 100°C
And second. The same question but for the aging of the device, rather than the stability in function of the temperature.
or for both conditions for the matter of the subject.
If someone can comment something about, I'll appreciate it !
Best Regards !

Dear Subhasis B :
Thank you for your answer sir,
sir, can you explain to me briefly what does it mean: "because of its mismatch of atom more likely to be in bridge head structure" ?
Do you mean the mismatch between two Graphene layers? or the mismatch between one Graphene layer and one of the layers of Bi2Te3 ?
And, What is the Bridge Head Structure ?
So. How does these two things (the mismatch and the BH structure) of the Graphene multilayer can affect the global stability of the system Bi2Te3 + Graphene nanoplatelets ?
I'm completely sure the answer I'm looking is to be found in this direction.
Regards ! :)
