文摘Experimental investigation on resonant tunneling in various GaAs/Al<sub>x</sub>Ga<sub>1-x</sub>Asdouble barrier single well structures has been performed by using tunneling spectroscopy atdifferent temperatures.The results show that in addition to resonant tunneling via GaAs wellstate confined by Al<sub>x</sub>Ga<sub>1-x</sub>As Γ-point barrier there exists resonant tunneling via GaAs well stateconfined by Al<sub>x</sub>Ga<sub>1-x</sub>As X-point barrier for both indirect(x】0.4)and direct(x【0.4)cases.
