Abstract
The energy splitting of two GaAs quantum wells coupled through a thin AlAs barrier (3–4 atomic layers) has been observed by resonant tunneling spectroscopy for the first time. The experimental result can be interpreted with calculations made by taking a Γ point for the AlAs barrier height and the envelope-function approximation.Keywords
