Experimental and theoretical values of energy gap and B . (a) Experimental values (diamonds) of energy gap in a-Ge QW versus thickness, fitted through effective mass theory (solid line). (b) Experimental values of B (diamonds, left axis) compared with the calculated trend [9] for the oscillator strength (O S ) in Ge QWs (line, right axis). Inset shows the linear correlation between B and O S .
