Kihm and Shin Publish in Nano Letters



Magnavox Professor Kenneth D. ihm and Assistant Professor Seungha Shin, who are both in the Department of Mechanical, Aerospace and Biome
dical Engineering, have published in a prestigious journal, Nano Letters, on “In-Plane Thermal Conductivity of Polycrystalline Chemical Vapor Deposition
Graphene with Controlled Grain Sizes,” ( This is the first experimental study that probed the grain size effect ongraphene thermal conductivity; the thermal conductivity of polycrystalline graphene was significantly reduced (from 5500 W/m×K to 680 W/m×K) when the grain size was
decreased from infinite down to 0.5 μm.  Kihm and Shin also theoretically elaborated this effective control through the ballistic size effect and grain boundary scattering.

The published work is based on international collaboration with Seoul National University where Kihm has advised multiple graduate students as an adjunct pr
