Abstract

We study the electron resonance tunneling through double quantum dots with different g factors. We found that the resonance tunneling current is suppressed even if one of the Zeeman sublevels is aligned. The level broadening effect partially releases the blockade. The current maximum peak appears when the interdot detune is half of Zeeman energy difference of two quantum dots.
