In this paper, we present a systematic study of the effect of growth parameters on the structural and optical properties of InAs quantum dot (QD) grown under Stranski-Krastanov mode by molecular beam epitaxy. The dot density is significantly reduced from 1 ...
Single photon sources have recently attracted significant interest for their potential role in the future applications of quantum cryptography, and in the longer term, quantum computing. Among the different types of single photon emitters, semiconductor qu ...
We present recent results of the study of surface properties and quantum efficiency (QE) of CsI photocathodes prepared on various substrates. Microanalysis methods provide laterally resolved surface morphology and chemical composition of the photoemissive ...
The influence of hydrostatic pressure on the emission and absorption spectra measured for various types of InGaN structures (epilayers, quantum wells, and quantum dots) is studied. While the known pressure coefficients of the GaN and InN band gaps are abou ...
High-efficiency top-emitting InGaAs/AlGaAs microcavity light-emitting diodes (MCLEDs) have been optimized and fabricated. The structures were grown using molecular beam epitaxy on GaAs substrates. They consist of a three-period Be-doped distributed Bragg r ...
Spatially resolved x-ray secondary electron photoemission spectra revealed lateral changes in quantum efficiency and chemical composition of polycrystalline cesium iodide photodetectors. Such changes depend on the substrate (stainless steel or aluminum). T ...
It is shown that both GaN and Ga0.8In0.2N quantum dots (QDs) can be grown by molecular beam epitaxy on silicon or sapphire substrates making use of the strain-induced two-dimensional (2D)-three dimensional (3D) growth mode occurring for mismatched material ...
Dissocn. efficiencies for excitation of the repulsive A 1P state of HCl were recorded in Xe, Kr, and Ar matrixes for photon energies between 5 and 10 eV from the content of dissocn. products and quantum efficiencies were derived with the absorption spectra ...
Charge sepn. in sintered colloidal TiO2 film electrodes was studied by action spectra in SCN-/(SCN)2- the UV region. Electrodes with different film thicknesses were studied. Current generation is most efficient close to the back contact. Monochromatic quan ...
The electron injection rate of bis(Bu4N) cis di(thiocyanato) bis (2,2'-bypiridine-4,4' carboxylic acid)Ruthenium (II) dye (N719) into SnO2 nanocryst. thin films was measured with 2-color femtosecond transient absorption spectroscopy. The electron injection ...
