WebIsolated interstitial hydrogen occurs either at the bond center ~BC! or at the tetrahedral interstitial site in c-Si. The former geometry is the lowest-energy configuration for H in the positive (H1) and neutral (H0) charge states; the latter is more favorable for H in the negative charge state (H2). Web1 λ = − ℜ( 1 n2 2 − 1 n2 1) Except for the negative sign, this is the same equation that Rydberg obtained experimentally. The negative sign in Equation 7.3.5 and Equation 7.3.6 indicates that energy is released as the electron moves from orbit n2 to orbit n1 because orbit n2 is at a higher energy than orbit n1.
