Abstract

We calculate hole energies of the bonding and antibonding states in coupled quantum wires using 6-band kp model. It is shown that hole ground state changes character from a bonding to an antibonding orbital with increasing inter-wire distances. This effect is a consequence of the enhancement of light hole contribution to the ground state. The variations of g factors under external electric and magnetic fields demonstrate the antibonding character of hole ground states.

► Orbital characters of hole ground state in coupled quantum wires are investigated. ► Transform from a bonding to an antibonding orbital is found for hole ground state. ► Variations of g factors under magnetic fields prove antibonding hole ground states.
