Optical signatures of lattice strain in chemically doped colloidal quantum wells by Junhong Yu, Hilmi Volkan Demir, Manoj Sharma

“…Abstract Lattice strain plays a vital role in tailoring the optoelectronic performance of colloidal nanocrystals (NCs) with exotic geometries. Although optical identifications of lattice strain in irregular-shaped NCs or hetero-structured NCs have been well documented, less is known about optical signatures of the sparsely distributed lattice mismatch in chemically-doped NCs. …”
