*.overlap

is the file output the electron and hole overlap with the 2D Schrodinger eigen solver. The output file format is

m,n, EigenEn(m),EigenEp(n),EigenEfn(m),EigenEfp(n), $|⟨{\varphi }_{e,m}|{\varphi }_{h,n}⟩|$

m is the mth electron eigen states
n is the nth hole eigen states
EigenEn(m)  is the $m_{th}$ electron eigen values
EigenEp(n)  is the $n_{th}$ hole eigen values
EigenEfn(m) is the averaged $m_{th}$ eigen wave function region's electon fermi level
EigenEfp(n) is the averaged $n_{th}$ eigen wave function region's hole's fermi level
$|⟨{\varphi }_{e,m}|{\varphi }_{h,n}⟩|$ is the overlap of mth electron and nth hole.
