Abstract
Pronounced oscillations have been observed in linewidth, amplitude, an d mass of electron cyclotron resonance in InAs/AlxGa1-xSb quantum well s when holes coexist with electrons. The strength of the oscillations increases sensitively with electron-hole pair density; the oscillation s are absent for semiconducting samples (x>0.3) in which there are no holes. Results are interpreted in terms of a filling-factor-dependent electron-hole interaction.
