Detection and Localization of Defects in Monocrystalline Silicon Solar Cell
solar cell electric signals combination of electric and optical methods
2011/4/21
Near-surface defects in solar cell wafer have undesirable influence upon device properties, as its efficiency and lifetime. When reverse-bias voltage is applied to the wafer, a magnitude of electric s...
Two-Photon Microscopy for the Observation of Internal Defects in Semiconductor Crystals in Three-Dimensions
Two-photon excitation Laser scanning microscopy Confocal microscopy
2009/6/12
We present a method of three-dimensional observation of internal defects in semiconductor crystals for blue lasers by use of two-photon process. We excite photoluminescence by using two-photon process...
Optical and electrical characterization of defects in zinc oxide thin films grown by atomic layer deposition
zinc oxide atomic layer deposition (ALD)
2011/5/11
In the present paper, we discuss the influence of point defects on electrical and optical characteristics of ZnO thin films grown by the atomic layer deposition (ALD) method. The films were grown on g...
Pressure induced microbends have been created in a 50 mm graded index multimode optical fibre with spatial periodicity L = 4.5 mm, embedded in the sample of araldite. If high pressure is applied direc...
Investigation of deep defects using generation-recombination noise
generation-recombination noise
2011/5/3
Noise spectroscopy is an effective tool to characterize the quality of semiconductor bulk and surface and a figure of merit for device quality as a whole. In certain cases, low-frequency noise can be ...
Capacitance-transient spectroscopy on irradiation-induced defects in Ge
Ge-defect deep level transient spectroscopy (DLTS) Laplace DLTS
2011/4/28
Recent studies of room-temperature irradiation-induced defects in Ge using space-charge capacitance-transient spectroscopy are reviewed. From these measurements only two defect complexes have been una...

Properties and origin of oval defects in epitaxial structures grown by molecular beam epitaxy
oval defects A3B5 molecular beam epitaxy (MBE) spectrally resolved photoluminescence
2011/4/27
A class of macroscopic, so-called oval defects, which may be found in an epitaxial A3B5 materials grown by molecular beam epitaxy (MBE) technique, is studied in this paper. The investigations were per...
Creating large bandwidth line defects by embedding dielectric waveguides into photonic crystal slabs
bandwidth line defects embedding dielectric waveguides photonic crystal slabs
2015/8/11
We introduce a general designing procedure that allows us, for any given photonic crystal slab, to create an appropriate line defect structure that possesses single-mode bands with large bandwidth and...
