Journal ArticleDOI
Soft X-ray microscopy at a spatial resolution better than 15 nm
Weilun Chao,Weilun Chao,Bruce Harteneck,J. Alexander Liddle,Erik H. Anderson,David Attwood,David Attwood +6 more
TL;DR: The achievement of sub-15-nm spatial resolution with a soft X-ray microscope—and a clear path to below 10 nm—using an overlay technique for zone plate fabrication is reported.
Journal ArticleDOI
Integration of Colloidal Nanocrystals into Lithographically Patterned Devices
Yi Cui,Mikael Björk,J. Alexander Liddle,Carsten Sönnichsen,Benjamin Boussert,A. Paul Alivisatos +5 more
TL;DR: In this paper, a facile method for reproducibly fabricating large-scale device arrays, suitable for nanoelectronics or nanophotonics, that incorporate a controlled number of sub-50-nm-diameter nanocrystals at lithographically defined precise locations on a chip and within a circuit is presented.
Journal ArticleDOI
Nanomanufacturing: A Perspective
TL;DR: This work considers the factors involved in matching processes with products, examining the characteristics and potential of top-down and bottom-up processes, and their combination, and how a careful assessment of the way in which function can be made to follow form can enable high-volume manufacturing of nanoscale structures with the desired useful, and exciting, properties.
Journal ArticleDOI
New Insights into Sequential Infiltration Synthesis
Jeffrey W. Elam,Mahua Biswas,Seth B. Darling,Angel Yanguas-Gil,Jonathan D. Emery,Alex B. F. Martinson,Paul F. Nealey,Tamar Segal-Peretz,Qing Peng,Jonathan P. Winterstein,J. Alexander Liddle,Yu-Chih Tseng +11 more
TL;DR: Important details of the SIS process are elucidated, including TMA adsorption in PMMA occurs through a weakly-bound intermediate, and dynamic structural changes occur during the individual precursor exposures, which have important implications for applications such as SIS lithography.
Journal ArticleDOI
Soft X-ray microscopy of nanomagnetism
TL;DR: Magnetic materials with dimensions of a few tens of nanometers are important for the development of ultrahigh-density magnetic storage and sensor devices Magnetic microstructure largely determines functionality, and imaging of magnetic domains and magnetization reversal behavior is an outstanding challenge Magnetic X-ray microscopy makes it possible to investigate magnetization phenomena with elemental specificity and high spatial and temporal resolution as mentioned in this paper.
