Optimization of growth conditions of type-II Zn(Cd)Te/ZnCdSe submonolayer quantum dot superlattices for intermediate band solar cells
Intermediate band solar cells (IBSCs) have been predicted to be significantly more efficient than the conventional solar cells, but have not been realized to their full potential due to the difficulties related to the fabrication of practical devices. The authors report here on growth and characterization of Zn(Cd)Te/ZnCdSe submonolayer quantum dot (QD) superlattices (SLs), grown by migration e...

متن کاملFeasibility of submonolayer ZnTe/ZnCdSe quantum dots as intermediate band solar cell material system
Intermediate band solar cells can potentially have an efficiency of 63% under full solar concentration, but the material systems investigated until now are far from optimum and are fraught with growth related issues such as low quantum dot densities, presence of wetting layers, and strain driven dislocations. Also, incorporation of type-I quantum dots increases carrier recombination rates, resu...
متن کاملZn-Se-Te multilayers with submonolayer quantities of Te: Type-II quantum structures and isoelectronic centers
Detailed studies with spectral and time-resolved photoluminescence, photoluminescence excitation, and absorption spectroscopies show the formation of type-II quantum structures squantum dotsd in a Zn-Se-Te multilayer system with submonolayer quantities of Te. Moreover, it is shown that in addition to these quantum dots, Te isoelectronic centers are also present in the same material system and c...
متن کاملMiniband formation engineering in GaN/AlN constant total effective radius multi-shells quantum dots and rings with on-center hydrogenic donor impurities
In this work, we have studied the miniband and minigaps of GaN/AlN constant total effective radius multi-shells quantum dots (CTER-MSQDs) and Rings (CTERMSQRs).We have investigated effects of the Hydrogenic donor impurities, quantum dots and rings radii, and the number of wells on miniband formation by sub-band energy calculations. We show that in these systems, minigaps can be created and then...
