Fig. 1: Overview of the different colloidal synthesis methods developed in this work, from InAs cluster precursors (red) to near-bulk InAs QDs (dark brown)41,42.

a Synthesis of InAs cluster precursors via hot injection at reaction temperatures ranging from 110 to 180 °C. b Heat-up approach for growing small InAs seeds from InAs clusters. c Seeded growth and d seedless growth methods for synthesizing large near-bulk InAs QDs through multiple injection-annealing cycles.
