Dimensional Analysis of Exciton Lifetime/Exciton Radiative Recombination Rate
Posted: Thu Nov 23, 2023 1:47 pm
Hi,
I am interested in finding the exciton lifetime using Yambo code. For the same I am referencing the following papers: https://journals.aps.org/prb/abstract/1 ... 100.075135 and https://iopscience.iop.org/article/10.1 ... 48X/ab5563 also few others.
From the formulas of Exciton lifetimes for each dimensional cases is coming out to be kg-second, rather than second. I have taken everything in SI units and the dielectric constant as unitless. Can you help me regarding the extra "kg" which is hovering around units of lifetime. Or am I missing something.
Regards,
Jagjit
