Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Heat Transfer in Gaseous Microflows: Conjugate Heat Transfer, Rarefaction and Compressibility Effects

, 2016
Development of Conjugate Heat Transfer models to study the behavior of heat exchange in gaseous microflows. At the scales considered, rarefaction effects play a relevant role so that the need to involve slip flow boundary conditions is fundamental. The wide development of MEMS application, the very fast development in microfabrication technologies, and

Non‐Monotonic Changes in the Thermal Conductivity of Conjugated Polymer Films with Increasing Levels of Chemical Doping

Advanced Functional Materials, EarlyView.
Thermal conductivity changes non‐monotonically as regioregular (RR) and regiorandom (RRa) P3HT films are doped with F4TCNQ as a function of the extent to which P3HT is doped: an increase in thermal conductivity is observed upon lightly doping P3HT compared to the undoped film, followed by a decrease in the heavily doped regime. ABSTRACT The performance
