Journal ArticleDOI
MoS$_{2}$ pixel arrays for real-time photoluminescence imaging of redox molecules.
Michael Reynolds,Marcos H. D. Guimarães,Hui Gao,Kibum Kang,Alejandro J. Cortese,Daniel C. Ralph,Jiwoong Park,Paul L. McEuen +7 more
TL;DR: In this paper, the photoluminescence of pixel arrays of an atomically thin two-dimensional (2D) material, a monolayer of MoS$2}$, can image spatial and temporal changes in redox molecule concentration in real time.
Journal ArticleDOI
The MoSeS dynamic omnigami paradigm for smart shape and composition programmable 2D materials.
TL;DR: A new approach, combining phase/strain engineering with shape programming, to form 3D objects by patterned alloying of 2D transition metal dichalcogenide (TMD) monolayers, which provide control of both bending and stretching deformations, are reversibly actuatable with electric fields, and possess the extraordinary and diverse properties of TMDs.
Journal ArticleDOI
Origin of second-order nonlinear optical response of polarity-controlled ZnO films
Jiwoong Park,Yoshiki Yamazaki,Yoshihiro Takahashi,Sung-Kwon Hong,Jiho Chang,Takumi Fujiwara,Takafumi Yao +6 more
TL;DR: In this article, the effect of grain size and surface roughness on the deff of polarity-controlled ZnO thin films for second harmonic generation has been investigated, and the correlation among the grain sizes and surface roughens with the values of deff was found strong.

Covalent organic framework films, and making methods and uses thereof
William R. Dichtel,Jiwoong Park,Arnab Mukherjee,Mark Levendorf,Arthur R. Woll,Eric L. Spitler,John Colson +6 more
TL;DR: In this article, a multilayer structure comprising a covalent organic framework (COF) film in contact with a polyaromatic carbon (PAC) film is proposed.
Journal ArticleDOI
Spatiotemporal Mapping of Photocurrent in a Monolayer Semiconductor Using a Diamond Quantum Sensor
Brian B. Zhou,Paul C. Jerger,Kan-Heng Lee,Masaya Fukami,Fauzia Mujid,Jiwoong Park,David D. Awschalom +6 more
TL;DR: In this paper, a contact-free method to spatially resolve local photocurrent densities using a proximal quantum magnetometer is introduced, which can achieve sensitivities to alternating current densities as small as 20 nA per micron.
