Noise in MgO barrier magnetic tunnel junctions with CoFeB electrodes; influence of annealing temperature
(American Institute of Physics, 2007)
Low frequency noise has been measured in magnetic tunnel junctions with MgO barriers and
magnetoresistance values up to 235%. The authors investigated the noise for different degrees of
crystallization and CoFeB/MgO ...
Liquid Phase Exfoliation of 2D Materials under Ambient Conditions
(Trinity College Dublin. School of Physics. Discipline of Physics, 2021)
A technique developed by the Coleman group in 2008 called liquid phase exfoliation (LPE) has been shown to be effective for the delamination of any material exhibiting a layered structure. Molybdenum dioxide ...
Analysis of slot characteristics in single mode semiconductor lasers using the 2D scattering matrix method
(IEEE, 2006)
We use the two-dimensional (2-D) scattering matrix method (SMM) to analyze the slot characteristics in slotted single-mode semiconductor lasers and compare the results with those calculated by the one-dimensional transfer ...
Charging, doping and gating of a single dangling bond on a bare Si(100)-c(4x2) surface
(Trinity College (Dublin, Ireland). School of Physics, 2012)
Despite the increasing interest in novel materials for the next generation of microelectronic devices, such as graphene and topological insulators, Si(100) surface is still the most important substrate for nano-device ...
Microwave-assisted synthesis of icosahedral nickel nanocrystals
(2011)
Nickel nanocrystals with icosahedral morphologies have been successfully synthesised using a microwave-assisted irradiation method. Nickel acetylacetonate was used as the metal precursor, while sodium formate and ...
The Design, Characterisation and Athermalisation of Vernier Widely Tunable Semiconductor Lasers
(Trinity College Dublin. School of Physics. Discipline of Physics, 2023)
The early 21st century has seen a surge in demand for communications technologies,
particularly with the internet having become a near essential utility in recent years. The
rise of high-resolution video streaming, among ...
Metallic Nitride and Carbide Perovskites: History and Prospects
(2022)
Energy-level diagrams for cubic metallic Fe4N and Mn4N were proposed by Goodenough in the late 1960s. Fe4N is ferromagnetic, but Mn4N is ferrimagnetic with a large moment on Mnc at the cube corner site and a much smaller ...
First-Principles Prediction of a Room-Temperature Ferromagnetic Janus VSSe Monolayer with Piezoelectricity, Ferroelasticity, and Large Valley Polarization
(2019)
Inspired by recent experiments on the successful fabrication of monolayer Janus transition-metal dichalcogenides [Lu, A.-Y.; Nat. Nanotechnol. 2017, 12, (8), 744 and ferromagnetic VSe2 [Bonilla, M.; Nat. Nanotechnol. 2018, ...
Magnetoresistance in magnetic tunnel junctions with amorphous electrodes
(IEEE, 2005)
Magnetic tunnel junctions (MTJs) with amorphous CoFeB and Co2MnSi electrodes were fabricated and examined. In the case of
[Co90Fe10]100 B , the = 32%boron addition reduces the magnetization by 30% compared to Co90Fe10, ...
Liquid phase exfoliation of carbonate-intercalated layered double hydroxides
(2019)
Direct exfoliation of a carbonate layered double hydroxide (LDH) has been achieved by using a novel horn-probe sonic tip, avoiding the development of time-consuming anion-exchange reactions. The most suitable solvents were ...
