| Abstract: | New lines shapes, not predicted by Stark broadening, are reported for 1s→2p (m=?1, 0) for a single hydrogenlike donor in InP. Stark-effect inhomogeneous broadening is suppressed by a magnetic field in GaAs according to both theory and experiment but the characteristic low frequency tail is enhanced by the high magnetic field for both 1s→2p (m=?1, 0) in InP. |
