Influence on miniband structure of size variations in regimented InAs/GaAs quantum dots arrays

Abstract

Electron emission properties of relaxation-induced traps in InAs/GaAs quantum dots and the effect of electronic band structure

Efficient, non-stochastic, Monte-Carlo-like-accurate method for the calculation of the temperature-dependent mobility in nanocrystal films

“…All calculations so far have been carried out assuming the 'defect' dots to represent 1% of the total number of dots in the array. This value is not too far from present experimental capabilities 1 , and well within the limits of applicability of our model 29,30 , where we assume no correlations between defects. The effect of varying the defect ratio from 0.5% to 8%, is shown in Fig.…”

Electronic properties of multi-ablooms flower-like quantum dots: a 2-D finite element study

“…Because of vast applications in science and technologies, during last few years, quantum dots (QDs) have been an appealing field study. During last few years, a wide variety of shapes, such as quantum dots arrays [1], conical [2], rectangular [3], cylindrical [4], disc-shaped [5], elliptical [6], lens-shaped [7], pyramidal [8], spherical [9], T-shaped [10], Y-shaped [11], etc., for the quantum dot systems have been studied. But as we know up to now, the electronic inter-sub-band structures of nanoflower systems [25] has not so far been addressed.…”

Band-like electron transport in 2D quantum dot periodic lattices: the effect of realistic size distributions

“…However, the much improved quality of recently sinthesized quantum dot superlattices could, in principle, enable the presence of extended electronic states and the consequent formation of energy miniband structures. A model to describe band-like transport See DOI: 10.1039/cXCP00000x/ ‡ CITIC-UGR, C/ Periodista Rafael Gómez Montero, 2, Granada, Spain is therefore required, and the relation between miniband structure features and predicted carrier mobilities should be investigated [28][29][30] . A recent work assumes the mobility in a band-like transport regime to be limited by the defects in the periodic arrangement, mainly size variation due to size dispersion in the quantum dot ensembles 31 .…”
