GaInN Quantum Wells as Optoelectronic Transducers for Biosensing of Ferritins
نویسنده
چکیده
In this work, investigations on gallium indium nitride (GaInN) quantum well structures as optochemical transducers in biosensing are presented. In contrast to the conventional electrical read-out of III-nitride-based sensors, a purely optical photoluminescence read-out is performed. Particularly, optical investigations of the iron-storage molecule ferritin deposited on GaInN quantum wells are presented. A significant spectral shift of the quantum well photoluminescence is observed for varying iron-load of ferritin.

Efficiency Studies of Semipolar GaInN-GaN Quantum Well Structures
In order to clarify the reasons for the fairly poor electroluminescence (EL) performance of semipolar LED structures grown on patterned sapphire wafers, we have analyzed both, pure photoluminescence (PL) test structures without doping only containing 5 GaInN quantum wells and full EL test structures, all emitting at a wavelength of about 510 nm. Evaluating the PL intensity over a wide range of ...

Uniaxial wurtzite group-III nitride heterostructures are subject to large polarization effects with significant consequences for device physics in optoelectronic and transport device applications. A central aspect for the proper implementation is the experimental quantification of polarization charges and associated fields. In modulated reflection spectroscopy of thin films and heterostructures...

In this work, position-controlled growth of nitrogen-polar Ga(In)N nanowire heterostructures with aspect ratios up to 20 is presented. By using nanoimprint lithography and dry etching techniques for the mask patterning, nanowires with diameters down to about 300 nm are grown by selective area metal organic vapor phase epitaxy. GaInN quantum wells are realized on the side facets of these structu...
متن کامل3D GaInN/GaN-based Green Light Emitters
The GaInN/GaN-based quantum wells (QWs) on one of the naturally stable semipolar facets (the {112̄2} facet) have inferior properties than those on the other (the {101̄1} facet). By optimizing the epitaxial growth conditions, the evolution of the {112̄2} facets of GaN inverse pyramids were successfully suppressed achieving a 50% higher photoluminescence (PL) intensity with even about 10 nm longer e...
متن کاملOptical Properties of GaInN/GaN Heterostructures and Quantum Wells
Photoreflection and photoluminescence spectroscopies have been used to identify details of the electronic bandstructure in GaInN/GaN strained heterostructures and multiple quantum well structures. Franz-Keldysh oscillations in the ternary layers are identified in both systems revealing large piezoelectric fields of 240 kV/cm (x=0.079, thin film) and 0.65 MV/cm (x=0.187). From spatially resolved...
