New paper published in Optics Letters

Jan 8, 2021

Graduate students Mansoor Sultan and Fatih Balli, along with professors Lau and Hastings, recently published their work describing metasurfaces that can simultaneously focus and filter light. These novel nanostructured optics may find application in imaging, spectroscopy, communications, or optical trapping.The work appears in Optics Letters (https://doi.org/10.1364/OL.410080) and was supported by the National Science Foundation and Intel Corp.

New e-print on arXiv: Switchable X-ray Orbital Angular Momentum from an Artificial Spin Ice

Dec 14, 2020

There is rapidly growing interest in X-ray orbital angular momentum (OAM) for imaging and probing materials at the nanoscale. Recently, a team of researchers spanning the University of Kentucky and Lawrence Berkeley, Argonne, and Brookhaven National Laboratories found that X-ray diffraction from an antiferromagnetic (AF) metasurface gives rise to X-ray photons carrying OAM.

New paper in Nanotechnology: Real-time dose control for electron-beam lithography

Dec 9, 2020

Former UK ECE graduate students Yugu Yang and Stephen Maloney recently published their work on "Real-time dose control for electron-beam lithography" in Nanotechnology. Electron-beam lithography is the primary patterning technique for integrated circuit mask making and low-volume manufacturing of nanoscale devices. The electron dose controls the critical dimensions of transistors and other nanoscale features. This paper describes the first step toward controlling this dose in real-time during patterning by using a fluorescent layer on the substrate.

New e-print on arXiv: Hybrid Metasurfaces for Simultaneous Focusing and Filtering

Sep 17, 2020

UK graduate students Mansoor Sultan and Fatih Balli recently released an e-print of their paper "Hybrid Metasurfaces for Simultaneous Focusing and Filtering." The paper described nanostructured, "flat" optics that simultaneously focus and filter light. Similiar devices could find application in conventional or hyperspectral imaging.The paper can be found at https://arxiv.org/abs/2009.07407.

National Nanotechnology Coordinated Infrastructure Award renewed for Kentucky Multiscale

Aug 24, 2020

The Kentucky Multiscale site of the National Nanotechnology Coordinated Infrastructure program was recently awarded a five year renewal by the National Science Foundation. Kentucky Multiscale is a consortium of shared facilities at the University of Louisville and the University of Kentucky that provide cutting-edge instrumentation and expertise in advanced manufacturing and characterization from the nanoscale to the macroscole. The award enables expanded access to the facilities along with a broad range of educational and outreach activities focused on nanoscale science and eng

Autovision 2020 to highlight Advanced Manufacturing Resources at the University of Kentucky and Louisville

Aug 1, 2020

The Autovision 2020 conference, hosted by the Kentucky Association of Manufacturers, will present a session on accessing advanced manufacturing resources at Kentucky Universities. This will include highlights from several Ky Multiscale NNCI cores and a panel discussion. The session is at 2pm on August 27, and Dr. Hastings will join the discussion with colleagues from UofL. More details can be found at the Autovision 2020 website.

Research from Hastings and De Long groups featured in Science Briefs from Lawrence Berkeley National Laboratory's Advanced Light Source

Jul 31, 2020

Lawrence Berkeley National Laboratory's Advanced Light Source recently featured work from Dr. Hastings' and Dr. De Long's research groups in their "Science Briefs." UK ECE postdoc Xiaoqian Chen and UK Physics graduate students Barry Farmer and Justin Woods took leading roles the effort which studied new phenomena in nanofabricated magnetic systems. The work was supported by the U.S. Department of Energy under Award Number DE-SC0016519.
