Verification of Bruno-Gnanasekar- Karunakaran- Chandramohan observation in non-magnetic semiconductor/diluted magnetic semiconductor heterostructure

Spin-dependent tunneling of light hole and heavy hole was discussed using transfer matrix method at the critical field where the potential of the heterostructure becomes zero. Bruno - Gnanasekar - Karunakaran - Chandramohan (BGKC) observed that the light hole travels faster than the heavy hole and the energy of resonance polarization for light hole is lower than the heavy hole [Eur. Phys. J. Plus (2017) 132: 279]. BGKC observation was verified at the critical magnetic field.
