Surface effects and the size-dependent hardening and strengthening of nickel micropillars
(PERGAMON-ELSEVIER SCIENCE LTD, 2012)
We evaluate the extent to which two mechanisms contribute to the observed size effect of the ultimate yield strength of micropillars of diameters in the range of 1-30 mu m: dislocation pile-ups, modeled by means of a ...
Micropillar Resonators for Optomechanics in the Extremely High 19-95-GHz Frequency Range
(American Physical Society, 2017-06)
Strong confinement, in all dimensions, and high mechanical frequencies are highly desirable for quantum optomechanical applications. We show that GaAs/AlAs micropillar cavities fully confine not only photons but also ...
Photonic computing with single and coupled spiking micropillar lasers

Effect of microfin surfaces on boiling heat transfer using HFE-7100 as working fluid
(2020-07-01)
One promising way to enhance the heat transfer coefficient (HTC) and the critical heat flux (CHF) is modifying the heating surface morphology by using machining techniques, coating, and chemical processes. Microstructured ...
Pool boiling heat transfer enhancement using micro-fin surfaces and dielectric fluids
(2020-01-01)
One promising way to enhance the heat transfer coefficient (HTC) and the critical heat flux (CHF) is modifying the heating surface morphology by using machining techniques, coating, and chemical processes. Microstructured ...
Optomechanical properties of GaAs/AlAs micropillar resonators operating in the 18 GHz range
(Optical Society of America, 2017-10-02)
Recent experiments demonstrated that GaAs/AlAs based micropillar cavities are promising systems for quantum optomechanics, allowing the simultaneous three-dimensional confinement of near-infrared photons and acoustic phonons ...
Study of semiconductor heterostructures with embedded quantum dots: micropillars and photodetectors
(Universidade Federal de Minas GeraisUFMG, 2009-07-16)
In this work, we study some of the optical processes that take place into semiconductor systems, specially heterostructures of two types with embedded quantum dots: infrared photodetectors and microcavity pillars. Quantum ...
Wettability control of polymeric microstructures replicated from laser-patterned stamps
(Nature Research, 2020-12)
In this study, two-step approaches to fabricate periodic microstructures on polyethylene terephthalate (PET) and poly(methyl methacrylate) (PMMA) substrates are presented to control the wettability of polymeric surfaces. ...
