In Kronig-Penney Model we seek solutions for time independent Scrödinger equation inside and outside of the periodic potential.(adsbygoogle = window.adsbygoogle || []).push({});

for 0 < x < a;V(x) =

V_{0}for -b < x < 0

My question is why solution of the KP Scrödinger equation in the region of [tex] -b < x < 0 [/tex] doesnot have complex exponentials as in the region of [tex] 0 < x < a [/tex] ?
