摘要：
With a large exciton Bohr radius and a high hole mobility in the bulk, GaSb is an important semiconductor material for technological applications. Here, we present a theoretical investigation into the evolution of some of its most fundamental characteristics at the nanoscale. GaSb emerges as a widely tunable, potentially disruptive new colloidal material with huge potential for application in a wide range of fields.
