nice vdo sir. kindly provide the references. from each material, we can calculate the direct and indirect band gap. How to identify that the material is shows which kind of band gap.
Which best book refer for this
Sir can we have negative value for ln apha values as you shown in video
As per existing in the literature...Yes it ll
@@NanoencryptionSKP my value are coming -ve not even single value is positive is my result wrong
@@JyotiSaini-v2h Have you confirm the there is no impurities in the sample?
why is column C not inside square?! only the alpha that is... should it be (E*Alpha)^2 and not E*Alpha^2?! min 4:50
Is it possible for a material to have 2 bandgap values?
K is absorbance? Since when?
