Magneto-optical investigations on cubic GaN in high magnetic fields

We report on direct IR–cyclotron resonance (CR) spectra of p-type cubic GaN (c-GaN) using semidestructive single-turn coil megagauss field generation. Two strong temperature dependent CR transitions were detected using measurement techniques with optimized signal to noise ratio resolving transmissio...

Summary:We report on direct IR–cyclotron resonance (CR) spectra of p-type cubic GaN (c-GaN) using semidestructive single-turn coil megagauss field generation. Two strong temperature dependent CR transitions were detected using measurement techniques with optimized signal to noise ratio resolving transmission changes smaller then 2%. On the basis of group theoretical relations between the valence-band energy-parameters of the effective Rashba–Sheka–Pikus Hamiltonian for the wurtzite and the effective Kohn–Luttinger Hamiltonian for the zincblende structure the Landau level scheme was calculated for c-GaN and compared with the observed transitions.
