Electronic properties of Sr14Cu24O41
(American Physical Society, 1989)
Crystals of orthorhombic Sr14Cu24O41 are semiconducting, with an activation energy of 0.18(2) eV for conduction along c, the direction lying parallel to both the (Cu2O3) planes and the (CuO2) chains. The magnetic susceptibility ...
Evaluation of STEM@University Experiences for Transition Year Students
(Trinity College Dublin. School of Physics. Discipline of Physics, 2022)
This master's monograph and research present a study on the influence of STEM@University (a non-formal, university-school intervention) on a Transition Year student's STEM identity, through the measurement of STEM capital, ...
Charge dynamics in the half-metallic ferromagnet CrO2
(American Physical Society, 1999)
Infrared spectroscopy is used to investigate the electronic structure and charge carrier relaxation in crystalline films of CrO2 which is the simplest of all half-metallic ferromagnets. Chromium dioxide is a bad metal at ...
Bacterially synthesized tellurium nanostructures for broadband ultrafast nonlinear optical applications
(2019)
Elementary tellurium is currently of great interest as an element with potential promise in nano-technology applications because of the recent discovery regarding its three two-dimensional phases and the existence of Weyl ...
A Hubble space telescope faint object spectrograph survey for broad absorption lines in a sample of low-redshift weak [O iii] quasi-stellar objects
(1997)
The study by Boroson & Meyers led to the suggestion that radio-quiet QSOs with weak [O III] and strong Fe II emission spectra form a class of QSOs that has a high probability of exhibiting broad absorption lines (BALs) in ...
MgO-based double barrier magnetic tunnel junctions with thin free layers
(American Institute of Physics, 2009)
The free layer thickness (tfree) in double barrier magnetic tunnel junctions (DMTJs) based on crystalline MgO barriers and CoFeB ferromagnetic layers has been varied from 0.5 to 3.0 nm in order to investigate its effect ...
Electrical detection of magnetic skyrmyons in a magnetic tunnel junction
(2022)
Magnetic skyrmions are promising information carriers for dense and energy-efficient information storage owing to their small size, low driving-current density, and topological stability. Electrical detection of skyrmions ...
Interface engineering of graphene nanosheet reinforced ZrB2 composites by tuning surface contacts
(American Physical Society (APS), 2019)
The mechanical properties of heterophase interfaces are critically important for the behavior of graphenereinforced
composites. In this work, the structure, adhesion, cleavage, and sliding of heterophase interfaces
formed ...
Surface modification on MoO2+x/Mo(110) induced by a local electric potential
(2019)
Oxygen adatoms on the MoO2+x/Mo(110) surface are observed to be removed when a sufficiently large bias is applied between the scanning tunneling microscope tip and the surface. Experimental observations, such as the bias ...
Broadband ultrafast nonlinear absorption and nonlinear refraction of layered molybdenum dichalcogenide semiconductors
