    1. Brief Introduction 

    Dr. EH Yang is a Professor in the Mechanical Engineering Department at Stevens Institute of Technology. The first to receive a MEMS Ph.D. in his native South Korea, he joined Stevens in 2006 following tenure as a senior member of the engineering staff at NASA Jet Propulsion Laboratory, where he was awarded, among other honors, the Lew Allen Award for Excellence for developing MEMS-based actuators and microvalves for large-aperture space telescopes and deformable mirrors capable of correcting for optical aberrations to improve high-resolution imaging. Through the Stevens Micro Device Laboratory, Dr. Yang facilitates student research and hands-on education in emerging nanotechnologies. In addition to his role as a faculty advisor of the nanotechnology graduate program, he spearheaded the design of Stevens' first undergraduate nanotechnology research-track training program. Dr. Yang has secured over 40 federal grants and contracts, including funding from the National Science Foundation, Air Force Office of Scientific Research, National Reconnaissance Office, US Army, and NASA. Dr. Yang's professional service credits include editorial or editorial board positions for several journals, including Nature’s Scientific Reports and multiple track chair positions for ASME International Mechanical Engineering Congress and Exposition (IMECE). He has produced more than 100 journal papers, 250 conference proceedings and presentations, and has delivered several keynotes or invited talks at major conferences.

    4. Research Areas

    4.1.Syntheses, Analyses and Applications of 2D Materials and Their Heterostructures

    There has been a growing interest in two-dimensional (2D) crystals beyond graphene, facilitating novel electronic and optoelectronic devices. Doping different atoms into transition metal dichalcogenides (TMDs) creates 2D dilute magnetic semiconductors, promising for spintronics applications. Our work synthesizes 2D dilute magnetic semiconductors via an in situ substitutional doping of metal atoms into the transition metal lattice sites in TMD monolayers and probes ferromagnetism at room temperature. These van der Waals ferromagnets find critical applications, including on-chip magnetic manipulation of quantum states or spintronics. Other related projects include modeling to prevent the anomalies encountered in topographic images of TMD monolayers in dynamic atomic force microscopy and elucidating the effect of TMD surfaces and their geometric arrangements on cellular morphology and adhesion. Suppose our growth and nanofabrication strategy could be developed to be highly reliable and high fidelity, in this case, it could have an enormous impact on the future research and commercialization of TMD-based devices.

    4.2. Flexible Electrodes and Tunable Wetting

    Skin-attachable electronic devices can be subjected to various lateral strains via stretching, bending, and distortion, while the devices must provide reliable outputs under pressure orthogonally applied to the surface. We perform partial-embedding of vertically aligned carbon nanotubes in polydimethylsiloxane, which are stable under stretching and bending (flexibility) for long-cyclic testing. The devices (e.g., pressure sensors) made using this process can be sensitive or insensitive to these lateral strains induced by mechanical deformation (such as stretching, bending, twisting, and wrinkling). We also utilize dodecylbenzenesulfonate-doped polypyrrole (PPy(DBS)) to provide additional functionalities to flexible sensors and energy-storage devices. Stretchable electrodes will have applications in wearable electronics, flexible photovoltaics (e.g., rolled-up displays), self-powered wearable optoelectronics, and electronic skins.
