We report a study of cyclotron resonance (CR) in a bilayer-bipolar InAs=GaSb structure and the in uence of the spatial separation between the electrons and holes. At low magnetic ÿelds we ÿnd that the cyclotron mass of the electrons can double when the electrons and holes have a very small separatio
