  Circularly-polarized magneto-photoluminescence (magneto-PL) technique has
been applied to investigate Zeeman effect in InAs/InGaAs/InAlAs quantum wells
(QWs) in Faraday geometry. Structures with different thickness of the QW
barriers have been studied in magnetic field parallel and tilted with respect
to the sample normal. Effective electron-hole g-factor has been found by
measurement of splitting of polarized magneto-PL lines. Lande factors of
electrons have been calculated using the 14-band kp method and g-factor of
holes was determined by subtracting the calculated contribution of the
electrons from the effective electron-hole g-factor. Anisotropy of the hole
g-factor has been studied applying tilted magnetic field.
