Structural and optical characterisation of MOVPE self-assembled InSb quantum dots in InAs and GaSb matrices
Transmission electron microscopy (TEM) and photoluminescence (PL) were used to study metal organic vapour phase epitaxy (MOVPE) self-assembled InSb quantum dots (QDs) grown for the first time in InAs and GaSb matrices. Coherently strained InSb QDs were observed in the InAs matrix sample with a numbe...

| description | Transmission electron microscopy (TEM) and photoluminescence (PL) were used to study metal organic vapour phase epitaxy (MOVPE) self-assembled InSb quantum dots (QDs) grown for the first time in InAs and GaSb matrices. Coherently strained InSb QDs were observed in the InAs matrix sample with a number density approximate to 3x10(9) cm(-2) and diameter 5-10 nn. PL emission was obtained at 3.5 mu m, the longest wavelength yet reported for self-assembled semiconductor QDs. Coherently strained InSb QDs were also observed in the GaSb matrix sample together with larger relaxed InSb islands. |
