Strmé InAs/GaAs heteropřechody a velmi tenké kvantové jámy vypěstované pomocí MOVPE
Hulicius, Eduard ; Pacherová, Oliva ; Oswald, Jiří ; Hospodková, Alice ; Pangrác, Jiří ; Šimeček, Tomislav ; Melichar, Karel ; Petříček, Otto ; Chráska, T. ; Holý, V. ; Vávra, I. ; Ouattara, L.
We have found that the abruptness and symmetry on monoatomic scale is achievable with MOVPE technique as well. We are able to find only the periodicity in these structures while atomic resolution pictures give reliable thickness values.
InAs/GaAs quantum-size structures grown by MOVPE
Hospodková, Alice ; Hulicius, Eduard ; Oswald, Jiří ; Pangrác, Jiří ; Šimeček, Tomislav
Structures with quantum size objects as self-organised quantum dots, quantum rings, wires and quasi-quantum wells could be reproducibly grown by MOVPE. The advantage of MOVPE technology is its material variability, operating costs and relation to the industry.
Characterization of lasers with ë-InAs layers in GaAs
Hazdra, P. ; Voves, J. ; Oswald, Jiří ; Hulicius, Eduard ; Pangrác, Jiří ; Melichar, Karel ; Šimeček, Tomislav ; Petříček, Otto ; Kuldová, Karla
The dependence of the electroluminescence spectra on the number of ë-InAs layers and on the distance of these ë-InAs layers was studied under pulse excitation in the wide range of current densities.
