Electric field tunable electron g factor and high asymmetrical Stark effect in InAs[sub 1−x]N[sub x] quantum dots
The electronic structure, electron g factor, and Stark effect of InAs1−xNx quantum dots are studied by using the ten-band k· p model. It is found that the g factor can be tuned to be zero by the shape and size of quantum dots, nitrogen N doping, and the electric field. The N doping has two effec...

Summary: | The electronic structure, electron g factor, and Stark effect of InAs1−xNx quantum dots are studied
by using the ten-band k· p model. It is found that the g factor can be tuned to be zero by the shape
and size of quantum dots, nitrogen N doping, and the electric field. The N doping has two effects
on the g factor: the direct effect increases the g factor and the indirect effect decreases it. The Stark
effect in quantum ellipsoids is high asymmetrical and the asymmetry factor may be 319. |
