Size and temperature dependent intraband optical studies of heavily n-doped PbS quantum dot solids

12 Jan 2020 Ramiro Iñigo Kundu Biswajit Dalmases Mariona Özdemir Onur Pedrosa María Konstantatos Gerasimos

Steady-state access to intraband transitions in colloidal quantum dots (CQDs), via heavy doping, allows exploiting the electromagnetic spectrum at energies below the band gap. CQD intraband optoelectronics opens up a new path to cheap mid- and long-wavelength infrared photodetectors and light-emitting devices, which today employ mostly epitaxial materials... (read more)
