Mechanisms of Stranski-Krastanov Growth
Stranski-Krastanov (SK) growth is reported experimentally as the growth mode that is responsible for the transition to three dimensional islands in heteroepitaxial growth. A kinetic Monte Carlo (KMC) model is proposed that can replicate many of the experimentally observed features of this growth mode. Simulations reveal that this model effectively captures the SK transition and subsequent growt...
متن کاملStranski–Krastanov growth of InGaN quantum dots emitting in green spectra
Self-assembled InGaN quantum dots (QDs) were grown on GaN templates by metalorganic chemical vapor deposition. 2D–3D growth mode transition through Stranski–Krastanov mode was observed via atomic force microscopy. The critical thickness for In0.67Ga0.33N QDs was determined to be four monolayers. The effects of growth temperature, deposition thickness, and V/III ratio on QD formation were examin...
متن کاملCoherent Stranski-Krastanov growth in 1¿1 dimensions with anharmonic interactions: An equilibrium study
The formation of coherently strained three-dimensional ~3D! islands on top of the wetting layer in the Stranski-Krastanov mode of growth is considered in a model in 1 1 1 dimensions accounting for the anharmonicity and nonconvexity of the real interatomic forces. It is shown that coherent 3D islands can be expected to form in compressed rather than expanded overlayers beyond a critical lattice ...
متن کاملSi/Ge intermixing during Ge Stranski–Krastanov growth
The Stranski-Krastanov growth of Ge islands on Si(001) has been widely studied. The morphology changes of Ge islands during growth, from nucleation to hut/island formation and growth, followed by hut-to-dome island transformation and dislocation nucleation of domes, have been well described, even at the atomic scale, using techniques such as scanning tunneling microscopy and transmission electr...
متن کاملModified Stranski-Krastanov growth in Ge/Si heterostructures via nanostenciled pulsed laser deposition.
The combination of nanostenciling with pulsed laser deposition (PLD) provides a flexible, fast approach for patterning the growth of Ge on Si. Within each stencilled site, the morphological evolution of the Ge structures with deposition follows a modified Stranski-Krastanov (SK) growth mode. By systematically varying the PLD parameters (laser repetition rate and number of pulses) on two differe...
