Resonant Light Absorption by Semiconductor Quantum Dots
Light Absorption quantum wells Semiconductor Quantum Dots
2009/9/4
The cross-section of light absorption by size-quantized semiconductor quantum dots (QD) is calculated in the case of a resonance with an exciton Γ6×Γ7 in cubical crystals of Td class. The interference...
Two-photon Absorption Processes in Semiconductor Quantum Dots
Nonlinear absorption Two-photon absorption Quantum dots
2010/9/29
The two-photon absorption process is a nonlinear phenomenon that shows very low optical efficiency in bulk
semiconductors. For this reason the detection of these processes becomes very difficult from...
Magnetic Field Induced Absorption in PbxEu1-xTe Magnetic Semiconductors
Magnetic Field Absorption PbxEu1-xTe Magnetic Semiconductors
2010/10/22
We report an investigation of the optical absorption spectrum, using non-polarized light, in PbxEu1¡xTe, x=0 and x=0.095, epitaxial thick layers grown by molecular beam epitaxy (MBE). The absorp...
