Modulation Doping of Silicon using Aluminium-induced Acceptor States in Silicon Dioxide.

Scientific reports

König D, Hiller D, Gutsch S, Zacharias M, Smith S.
PMID: 28425460
Sci Rep. 2017 Apr 20;7:46703. doi: 10.1038/srep46703.

All electronic, optoelectronic or photovoltaic applications of silicon depend on controlling majority charge carriers via doping with impurity atoms. Nanoscale silicon is omnipresent in fundamental research (quantum dots, nanowires) but also approached in future technology nodes of the microelectronics...

Laboratory assessment of thermal characteristics of three phacoemulsification tip designs operated using torsional ultrasound.

Clinical ophthalmology (Auckland, N.Z.)

PMID: 27358554
Clin Ophthalmol. 2016 Jun 13;10:1095-101. doi: 10.2147/OPTH.S105065. eCollection 2016.

PURPOSE: Ultrasound activation of phacoemulsification (phaco) tips can create considerable thermal energy that may increase the risk of tissue damage during cataract surgery. The purpose of this study was to define the thermal profiles of three phaco tip designs...

Successive spin polarizations underlying a new magnetic coupling contribution in diluted magnetic semiconductors.

Journal of physics. Condensed matter : an Institute of Physics journal

Andriotis AN, Fthenakis ZG, Menon M.
PMID: 25614683
J Phys Condens Matter. 2015 Feb 11;27(5):052202. doi: 10.1088/0953-8984/27/5/052202. Epub 2015 Jan 23.

We propose a new type of magnetic coupling (MC) that is found in diluted magnetic semiconductors (DMSs). The origin of this is found to be the result of charge transfer processes followed by successive spin polarizations (SSPs) along successive...

Stochastic Approach to Phonon-Assisted Optical Absorption.

Physical review letters

Zacharias M, Patrick CE, Giustino F.
PMID: 26551142
Phys Rev Lett. 2015 Oct 23;115(17):177401. doi: 10.1103/PhysRevLett.115.177401. Epub 2015 Oct 19.

We develop a first-principles theory of phonon-assisted optical absorption in semiconductors and insulators which incorporates the temperature dependence of the electronic structure. We show that the Hall-Bardeen-Blatt theory of indirect optical absorption and the Allen-Heine theory of temperature-dependent band...

A symptom-based approach to treatment of psychosis in autism spectrum disorder [corrected].

BJPsych open

Bell V, Dunne H, Zacharia T, Brooker K, Shergill S.
PMID: 29388910
BJPsych Open. 2018 Jan;4(1):1-4. doi: 10.1192/bjo.2017.2.

The optimal management of autism with psychosis remains unclear. This report describes a 22-year-old man with autism and psychosis who was referred to a tertiary-level specialist psychosis service, following a 6-year history of deterioration in mental health starting around...

Equiatomic AEAuX (AE=Ca-Ba, X=Al-In) Intermetallics: A Systematic Study of their Electronic Structure and Spectroscopic Properties.

Chemistry (Weinheim an der Bergstrasse, Germany)

Benndorf C, Stegemann F, Seidel S, Schubert L, Bartsch M, Zacharias H, Mausolf B, Haarmann F, Eckert H, Pöttgen R, Janka O.

The three intermetallic compounds SrAuGa, BaAuAl and BaAuGa were synthesised from the elements in niobium ampoules. The Sr compound crystallises in the orthorhombic KHg

Enhanced adaptive focusing through semi-transparent media.

Scientific reports

Di Battista D, Zacharakis G, Leonetti M.
PMID: 26620906
Sci Rep. 2015 Dec 01;5:17406. doi: 10.1038/srep17406.

Adaptive optics can focus light through opaque media by compensating the random phase delay acquired while crossing a scattering curtain. The technique is commonly exploited in many fields, including astrophysics, microscopy, biomedicine and biology. A turbid lens has the...

Graphene allotropes under extreme uniaxial strain: an ab initio theoretical study.

Fthenakis ZG, Lathiotakis NN.
PMID: 26051043
Phys Chem Chem Phys. 2015 Jul 07;17(25):16418-27. doi: 10.1039/c5cp02412a. Epub 2015 Jun 05.

Using density functional theory calculations, we study the response of three representative graphene allotropes (two pentaheptites and octagraphene) as well as graphene, to uniaxial strain up to their fracture limit. Those allotropes can be seen as distorted graphene structures...

Atomic-layer-deposition alumina induced carbon on porous Ni(x)Co(1-x)O nanonets for enhanced pseudocapacitive and Li-ion storage performance.
