Dislocation-induced structural and luminescence degradation in InAs quantum dot emitters on silicon

Autor: Hughes, Eamonn T., Kusch, Gunnar, Selvidge, Jennifer, Bonef, Bastien, Norman, Justin, Shang, Chen, Bowers, John E., Oliver, Rachel A., Mukherjee, Kunal

We probe the extent to which dislocations reduce carrier lifetimes and alter luminescence and growth morphology in InAs quantum dots (QD) grown on silicon. These heterostructures are key ingredients to achieving a highly reliable monolithically integ

Epitaxial thin films of the substitutionally alloyed half-Heusler series CoTi$_{1-x}$Fe$_x$Sb were grown by molecular beam epitaxy on InAlAs/InP(001) substrates for concentrations 0.0$\leq$x$\leq$1.0. The influence of Fe on the structural, electronic

Localization landscape theory of disorder in semiconductors II: Urbach tails of disordered quantum well layers

Autor: Piccardo, Marco, Li, Chi-Kang, Wu, Yuh-Renn, Speck, James S., Bonef, Bastien, Farrell, Robert M., Filoche, Marcel, Martinelli, Lucio, Peretti, Jacques, Weisbuch, Claude

Publikováno v: Phys. Rev. B 95, 144205 (2017)

Urbach tails in semiconductors are often associated to effects of compositional disorder. The Urbach tail observed in InGaN alloy quantum wells of solar cells and LEDs by biased photocurrent spectroscopy is shown to be characteristic of the ternary a
