Biography:

Dr. Yung Joon Jung is Professor at Northeastern University, Department of Mechanical and Industrial Engineering and co-faculty director at Kostas Advanced Nano Characterization Center at Kostas Research Institute, Northeastern University. He received Ph.D. in Materials Engineering from Rensselaer Polytechnic Institute, 2003. He worked as a Postdoctoral Fellow at Rensselaer, and joined Northeastern University at 2005. Prof. Jung’s research focuses on investigating new synthetic routes for low dimensional nanomaterials and engineering their molecular structures. He also develops nanomanufacturing processes such as assembly and integration of nanomaterials and nanostructured architectures for nanoelectronics, flexible devices, various sensors and energy storage applications supported by National Science Foundation, Department of Defense, US Army, Ministry of Industry in Republic of Korea and other industries. He published over 65 articles in journals and three book chapters. He is also a co-founder of Guradion Technologies that develop networkable high performance ion and radiation sensors.

Abstract:

Over the past two decades, researches on low-dimensional carbon nanostructured materials (SWCNT and graphene) designed for a variety of sensor applications have made remarkable progress. However scalable fabrication and engineering of high performance sensors that harness 2-3 dimensional nano/micro architectures of these nanomaterials have remained largely elusive. Such methodologies will allow unprecedented device architectures fully utilizing superior physical and chemical properties of these nanomaterials for high performance and low SWaP sensors. Here we present some of our progresses in assembly and engineering of singlewalled nanotube networks and building 2-3D architectures for broad ranges of high performance chemical, optical and ion sensors by combining state-of-the-art assembly and transfer based nanomanufacturing strategies developed in our laboratory.

Abstract:

The extreme light confinement provided by sub-wavelength metal-dielectric structures pushes towards revisiting the design rules of the photo-detectors. Furthermore, introducing absorbing layers in optical nano-resonators demands a dedicated electromagnetic design. Developing together semiconducting heterostructures and optical nano-antennas opens the way for performance improvements and new functionalities, introducing very promising features such as ultra-thin absorbing layers and device area much smaller than its optical cross-section. High responsivity, high-speed behavior, and carved optical response are among the expected properties of this new generation of photo-detectors.
 
In this talk, I present a GMR InGaAs photo-detector dedicated for imaging applications (FPA) as an illustration of this global design. I discuss the cross-linked properties of the optical and semiconductor structures. Experimental results show at λ = 1.55 μm an external quantum efficiency (EQE) of 75% and a specific detectivity of 1013 cm.√Hz.W-1.

Abstract:

Two-dimensional (2D) materials such as graphene and transition metal dichacogenides (TMDCs) have unique physical and electrical properties. There is currently interest in taking advantage of these properties for future electronic applications. In this talk, I first introduce a modified chemical vapor deposition (CVD) technique for the production of large-area, high-quality continuous monolayer graphene films from benzene on Cu at 100–300 °C at ambient pressure. In this method, we extended the graphene growth step in the absence of residual oxidizing species by introducing pumping and purging cycles prior to growth. Further, Cu/graphene stacked interconnects are fabricated by directly synthesizing graphene onto Cu interconnects using this method, which show the improved electrical properties compared to Cu interconnects. In the second part, I present a simple and facile route to reversible and controllable modulation of the electrical and optical properties of WS2 and MoS2 via hydrazine doping and sulfur annealing. Hydrazine treatment of TMDSs improves the field-effect mobilities and photoresponsivities of the devices. These changes are fully recovered via sulfur annealing. This may enable the fabrication of 2D electronic and optoelectronic devices with improved performance.
