Inversion of Zeeman splitting of exciton states in InGaAs quantum wells
P. S. Grigoryev, O. A. Yugov, S. A. Eliseev +5
Zeeman splitting of quantum-confined states of excitons in InGaAs quantum wells (QWs) is experimentally found to depend strongly on quantization energy. Moreover, it changes sign w…
