Lattice-matched n-n ZnSe/In0.04Ga0.96As heterojunctions were studied b
y means of current density versus voltage (J-V) and capacitance versus
voltage (C-V) measurements. The resulting characteristics indicate th
at the behavior of this n-n heterostructure can be explained by a back
-to-back double Schottky diode model. The value of conduction band dis
continuity (Delta E-c) is found to be 0.10-0.12 eV. (C) 1998 American
