Can we talk about the qua confinement
Dear Abdellah,
To the best of my knowledge, you can talk about quantum confinement only when the particle size is of the order of atomic scales~few nm
Dear Tamás Haraszti Tank you for your answer. in fact, I measured band gaps of my samples by UV-visible absorption (these materials are dielectric, 3.6
Dear abdou
The confinement effect is obtained when the size is in order of the Broglie wave length Lb ie few nm.
We can separate three types of conf
1 strong conf if the size inf then Lb
2 low conf if size sup then Lb
3 medium when the Lb# size
In all cases the band gap depends on the size
See kayanuma or brus

Dear Mustapha thank you so much for this very important clarification.
can I introduce the parameters of the WLC model in Abaqus for studying the fracture behaviour of epoxy ?
