The effects of the intense laser field on donor impurities in a cylindrical GaxIn1-xNyAs1-y/GaAs quantum dot under the electric field
MetadataShow full item record
For different nitrogen and indium concentrations, intense laser field (ILF) effect on donor impurity binding energy in a cylindrical GaxIn1-xNyAs1-y/GaAs quantum dot (QD) has been studied. Results show that ILF creates an additional confinement on the electronic and impurity states in QD and increases nitrogen and indium concentration effects on electronic states.
