On way to ideal quantum dots
Temperature and concentration self-assembling conditions of tetrahedral 1Sb4Ga clusters in multi-valley zinc blende AlN:(Ga, Sb) in the ultra dilute Sb limit are represented. Tetrahedral clusters should occur as a result of the second-order transition. The final stage of self-assembling when all Sb atoms are in 1Sb4Ga clusters also has to be reached as a result of the second-order transition at finite temperatures.
