The properties of ultrapure delafossite metals
(2017-03) - Journal item,
Although they were first synthesized in chemistry laboratories nearly fifty years ago, the physical properties of the metals PdCoO2, PtCoO2 and PdCrO2 have only more recently been studied in detail. The delafossite structure ...
Colloidal nanocrystals : electrifying quantum dots for lasers
(2018-01) - Journal item,
Superdomain dynamics in ferroelectric-ferroelastic films : switching, jamming, and relaxation
(2017-12) - Journal item,
Recent experimental work shows that ferroelectric switching can occur in large jumps in which ferroelastic superdomains switch together, rather than having the numerous smaller ferroelectric domains switch within them. In ...
Ferroelectrics, multiferroics and artifacts : lozenge-shaped hysteresis and things that go bump in the night
(2018-06) - Journal item,
This review summarizes dielectric studies and related experiments on ferroelectrics and multiferroics about which there has been considerable controversy in the literature, sometimes at unusually impolite and unprofessional ...
Negative electronic compressibility and tunable spin splitting in WSe2
(2015-12) - Journal item,
Tunable bandgaps1, extraordinarily large exciton-binding energies2, 3, strong light–matter coupling4 and a locking of the electron spin with layer and valley pseudospins5, 6, 7, 8 have established transition-metal ...
Some current problems in perovskite nano-ferroelectrics and multiferroics : kinetically-limited systems of finite lateral size
(2015-06) - Journal item,
We describe some unsolved problems of current interest; these involve quantum critical points in ferroelectrics and problems which are not amenable to the usual density functional theory, nor to classical Landau free energy ...
Optothermal nonlinearity of silica aerogel
(2016-07-25) - Journal item,
We report on the characterization of silica aerogel thermal optical nonlinearity, obtained by z-scan technique. The results show that typical Silica Aerogels have nonlinear optical coefficient similar to that of glass (≃ ...
Spatial distribution of phase singularities in optical random vector waves
(2016-08-26) - Journal item,
Phase singularities are dislocations widely studied in optical fields as well as in other areas of physics. With experiment and theory we show that the vectorial nature of light affects the spatial distribution of phase ...
Chiral plasmonic nanostructures : twisted by DNA
(2014-09) - Journal item,
Direct and indirect measurements on electrocaloric effect : recent developments and perspectives
(2016-09) - Journal item,
It has been ten years since the discovery of the giant electrocaloric effect in ferroelectric materials showed that it is possible to employ this effect for substantial cooling applications. This last decade has been marked ...
