4D Visualization of Transitional Structures in Phase Transformations by Electron Diffraction
Complex systems in condensed phases involve a multidimensional energy landscape, and knowledge of transitional structures and separation of time scales for atomic movements is critical toExpand

Direct role of structural dynamics in electron-lattice coupling of superconducting cuprates
The mechanism of electron pairing in high-temperature superconductors is still the subject of intense debate. Here, we provide direct evidence of the role of structural dynamics, with selectiveExpand

Electrons in Finite-Sized Water Cavities: Hydration Dynamics Observed in Real Time
We directly observed the hydration dynamics of an excess electron in the finite-sized water clusters of \batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb}Expand

Optical production of metastable krypton
We have investigated a new scheme for excitation of the 5s, J = 2 metastable level of Kr (5s[3/2]J = 2) which can be readily extended to other rare gases. In the scheme, an ultraviolet (UV) lamp isExpand

Nonequilibrium Phase Transitions in Cuprates Observed by Ultrafast Electron Crystallography
Nonequilibrium phase transitions, which are defined by the formation of macroscopic transient domains, are optically dark and cannot be observed through conventional temperature- or pressure-changeExpand

4D scanning ultrafast electron microscopy: visualization of materials surface dynamics.
The continuous electron beam of conventional scanning electron microscopes (SEM) limits the temporal resolution required for the study of ultrafast dynamics of materials surfaces. Here, we report theExpand

Scanning ultrafast electron microscopy
Progress has been made in the development of four-dimensional ultrafast electron microscopy, which enables space-time imaging of structural dynamics in the condensed phase. In ultrafast electronExpand

Ultrafast electron crystallography. 1. Nonequilibrium dynamics of nanometer-scale structures
In this paper, the first in a series, we give a full account of the development of ultrafast electron crystallography (UEC) and its applications in the study of nanometer-scale semiconductors and t...

4D Electron Diffraction Reveals Correlated Unidirectional Behavior in Zinc Oxide Nanowires
The confined electronic structure of nanoscale materials has increasingly been shown to induce behavior quite distinct from that of bulk analogs. Direct atomic-scale visualization of nanowires ofExpand
