Towards defect-free 1-D GaAs/AlGaAs heterostructures based on GaAs nanomembranes.

Nanoscale

Tutuncuoglu G, de la Mata M, Deiana D, Potts H, Matteini F, Arbiol J, Fontcuberta i Morral A.
PMID: 26416625
Nanoscale. 2015 Dec 14;7(46):19453-60. doi: 10.1039/c5nr04821d. Epub 2015 Sep 29.

We demonstrate the growth of defect-free zinc-blende GaAs nanomembranes by molecular beam epitaxy. Our growth studies indicate a strong impact of As4 re-emission and shadowing in the growth rate of the structures. The highest aspect ratio structures are obtained...

Optimized Exchange and Correlation Semilocal Functional for the Calculation of Energies of Formation.

Journal of chemical theory and computation

Sarmiento-Pérez R, Botti S, Marques MA.
PMID: 26574465
J Chem Theory Comput. 2015 Aug 11;11(8):3844-50. doi: 10.1021/acs.jctc.5b00529.

We present a semiempirical exchange-correlation functional for density functional theory tailored to calculate energies of formation of solids. It has the same form of a Perdew-Burke-Ernzerhof functional, but three parameters have been fitted to reproduce experimental energies of formation...

Bistability in buckled dome microcavities.

Optics letters

Bitarafan MH, Ramp H, Potts C, Allen TW, Davis JP, DeCorby RG.
PMID: 26565878
Opt Lett. 2015 Nov 15;40(22):5375-8. doi: 10.1364/OL.40.005375.

We describe optical bistability in monolithically integrated, curved-mirror Fabry-Perot microcavities. The cavities were fabricated by controlled formation of circular delamination buckles within sputtered Si/SiO(2) multilayers. The dominant source of the bistability is heating due to residual absorption in the...

Synthesis, Morphological, and Electro-optical Characterizations of Metal/Semiconductor Nanowire Heterostructures.

Nano letters

Glaser M, Kitzler A, Johannes A, Prucnal S, Potts H, Conesa-Boj S, Filipovic L, Kosina H, Skorupa W, Bertagnolli E, Ronning C, Fontcuberta I Morral A, Lugstein A.
PMID: 27168031
Nano Lett. 2016 Jun 08;16(6):3507-13. doi: 10.1021/acs.nanolett.6b00315. Epub 2016 May 13.

In this letter, we demonstrate the formation of unique Ga/GaAs/Si nanowire heterostructures, which were successfully implemented in nanoscale light-emitting devices with visible room temperature electroluminescence. Based on our recent approach for the integration of InAs/Si heterostructures into Si nanowires...

Do epinephrine auto-injectors have an unsuitable needle length in children and adolescents at risk for anaphylaxis from food allergy?.

Allergy, asthma, and clinical immunology : official journal of the Canadian Society of Allergy and Clinical Immunology

Allergy Asthma Clin Immunol. 2016 Mar 06;12:11. doi: 10.1186/s13223-016-0110-8. eCollection 2016.

BACKGROUND: Food allergy is the most common cause of anaphylaxis in children. Intramuscular delivery of epinephrine auto-injectors (EAI) is the standard of care for the treatment of anaphylaxis. We examined if children and adolescents at risk of anaphylaxis weighing...

Estimating excitonic effects in the absorption spectra of solids: problems and insight from a guided iteration scheme.

Physical review letters

Rigamonti S, Botti S, Veniard V, Draxl C, Reining L, Sottile F.
PMID: 25910143
Phys Rev Lett. 2015 Apr 10;114(14):146402. doi: 10.1103/PhysRevLett.114.146402. Epub 2015 Apr 07.

A major obstacle for computing optical spectra of solids is the lack of reliable approximations for capturing excitonic effects within time-dependent density functional theory. We show that the accurate prediction of strongly bound electron-hole pairs within this framework using...

The planar-to-tubular structural transition in boron clusters from optical absorption.

The Journal of chemical physics

Marques MA, Botti S.
PMID: 16035838
J Chem Phys. 2005 Jul 01;123(1):014310. doi: 10.1063/1.1948386.

The optical response of the lowest-energy isomers of the B20 family is calculated using time-dependent density-functional theory within a real-space, real-time scheme. Significant differences are found among the absorption spectra of the clusters studied. We show that these differences...

Strong interplay between structure and electronic properties in CuIn(S,Se){2}: a first-principles study.

Physical review letters

Vidal J, Botti S, Olsson P, Guillemoles JF, Reining L.
PMID: 20366776
Phys Rev Lett. 2010 Feb 05;104(5):056401. doi: 10.1103/PhysRevLett.104.056401. Epub 2010 Feb 01.

We present a first-principles study of the electronic properties of CuIn(S,Se){2} (CIS) using state-of-the-art self-consistent GW and hybrid functionals. The calculated band gap depends strongly on the anion displacement u, an internal structural parameter that measures lattice distortion. This...
