Electronic and interface properties of polyfluorene films on GaN for hybrid optoelectronic applications
(2013)Electronic and interface properties of spin-coated poly(9,9- dioctylfluorenyl-2,7-diyl) (PFO) films on GaN have been investigated in terms of their potential for optoelectronic applications. The PFO/GaN interface was studied ...

Initial/final state selection of the spin polarization in electron tunneling across an epitaxial FeGaAs (001) interface
(2007)Spin dependent electron transport across epitaxial FeGaAs (001) interfaces has been investigated using photoexcitation techniques. Spin filtering is observed in the forward bias regime and its sign is switched by using ...

Reduction of spin injection efficiency by interface defect spin scattering in ZnMnSe/AlGaAs-GaAs spin-polarized light-emitting diodes
(2002)The effects of the interface microstructure on spin-injection efficiency in Zn1-xMnxSe/AlyGa1-yAs-GaAs spin-polarized light-emitting diodes (spin-LEDs) were studied. It was shown that the quantum well (QW) spin polarization ...

Structure, morphology, and photoluminescence of porous Si nanowires: Effect of different chemical treatments
(2013)The structure and light-emitting properties of Si nanowires (SiNWs) fabricated by a single-step metal-assisted chemical etching (MACE) process on highly boron-doped Si were investigated after different chemical treatments. ...
