Potenciál kvantových teček při detekci jediné molekuly v buňkách a organelách
Přikryl, Jan ; Klepárník, Karel ; Svobodová, Ivona ; Hezinová, Věra ; Lišková, Marcela ; Preisler, J. ; Foret, František
This contribution is devoted to quantum dots usage for cell imaging in fluorescence microscopy. Fluorescence excitation by evanescence wave (caused by total internal reflection) is compared with conventional epifluorescence microscopy.
Comprehensive and targeted proteomic analysis of red yeast Rhodotorula glutinis cultivated under normal and stressed condition
Hezinová, Věra ; Svobodová, Ivona ; Čarnecká, M. ; Halienová, A. ; Klepárník, Karel ; Márová, I.
The differences in proteomic profile of red yeast Rhodotorula glutinis cultivated under normal and stress condition were studied using two approaches; comprehensive and targeted. In targeted approach semiconductor quantum dots were used for protein visualization.
In situ monitorování růstu MOVPE InAs/GaAs struktur s kvantovými tečkami pomocí reflektanční anisotropické
Vyskočil, Jan ; Hospodková, Alice ; Pangrác, Jiří ; Melichar, Karel ; Oswald, Jiří ; Kuldová, Karla ; Mates, Tomáš ; Šimeček, Tomislav ; Hulicius, Eduard
Reflectance anisotropy spectroscopy (RAS) has been used for the real-time observation and optimization of single and double InAs/GaAs quantum dot layer structure growth. The properties of samples were ex situ characterized by photoluminescence and AFM.
Studie InAs/GaAs kvantových teček vypěstovaných technologií LP-MOVPE
Hazdra, P. ; Atef, M. ; Komarnitsky, V. ; Oswald, Jiří ; Kuldová, Karla ; Hulicius, Eduard
We show simulation study of electronic transition energy for InAs/GaAs quantum dots fabricated with LP-MOVPE. The simulation results were compared with experimental data obtained by AFM and photoluminescence.
Určení parametrů kvantových teček PbCl.sub.2./sub. v matrici NaCl pomoci optické spektroskopie
Sveshnikov, Alexey ; Demo, Pavel ; Polák, Karel ; Beitlerová, Alena ; Tichá, Petra ; Kožíšek, Zdeněk
Within context of nucleation theory and utilizing optical spectroscopy measurements at various temperatures the basic parameters entering nucleation equation (such as, for example, surface energy, resp. temperature dependent difference in chemical potentials) may be estimated.
Negibbovská stacionární elektronová distribuce v kvantových tečkách
Král, Karel ; Zdeněk, Petr
Experiments on relaxation and optical electronic properties of quantum dots are reviewed and conclusions are outlined on the use of Gibbs grand-canonical distribution in these structures
self-assembled quantum dots: electronic spectral densities
Král, Karel ; Zdeněk, Petr ; Khás, Zdeněk
Optical and transport properties of quantum dots are reported.
Ballistic electron emission microscopy of InAs quantum dots in AlGaAs/GaAs heterostructure
Vaniš, Jan ; Hulicius, Eduard ; Pangrác, Jiří ; Melichar, Karel ; Walachová, Jarmila
Ballistic electron emission measurements of InAs/GaAs quantum dots in AlGaAs/GaAs heterostructures are presented in our contribution. Measured heterostructure was prepared by MOCVD technique. The area of 1 μm.sup.2./sup. was analyzed during measurements. Different size and shape of quantum dots on an examined area were vizualized. The average size of quantum dots were 10 nm and less. The observed shapes are probably connected with density of states in quantum dots.
