The out-of-plane g-factor g perp for quasi-2D holes in a 100 GaAs heterostructure is studied using a variable width quantum wire. A direct measurement of the Zeeman splitting is performed in a magnetic field applied perpendicular to the 2D plane. We measure an out-of-plane g-factor up to g perp = 5, which is larger than previous optical studies of g perp, and is approaching the long predicted but never experimentally veri?ed out-of-plane g-factor of 7.2 for heavy holes.
