(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find donor-electron ionziation energy of silicon crystal. Electron effective mass m_{c}=.98m_{o}and dielectric constant ε/ε_{o}=12.3

2. Relevant equations

I use the E_{D}=-(1/4πε)^{2}*[(m_{c}*e^{4}) / (2*(h/2π)^{2})]

3. The attempt at a solution

My answer of -1.415x10^{-54}does not seem right. I solved for m_{c}and ε from given equations in the problem and plugged in. Is this correct or have I made a mistake?
