Cracking in polymer substrates for flexible devices and its mitigation
Anush Ranka, Madhuja Layek, Sayaka Kochiyama +11
Mechanical reliability plays an outsized role in determining the durability of flexible electronic devices because of the significant mechanical stresses they can experience during…
Elastic Modulus of Polycrystalline Halide Perovskite Thin Films on Substrates
Madhuja Layek, In Seok Yang, Zhenghong Dai +5
Using an innovative combination of multi-beam-optical stress-sensor (MOSS) curvature and X-ray diffraction (XRD) techniques, the Young's modulus (E) of polycrystalline MAPbI3 metal…
Time-resolved vibrational-pump visible-probe spectroscopy for thermal conductivity measurement of metal-halide perovskites
Shunran Li, Zhenghong Dai, Linda Li +2
Understanding thermal transport at the micro- to nanoscale is crucially important for a wide range of technologies ranging from device thermal management and protection systems to…
Photothermally induced, reversible phase transition in methylammonium lead triiodide
Shunran Li, Zhenghong Dai, Conrad A. Kocoj +3
Metal halide perovskites (MHPs) are known to undergo several structural phase transitions, from lower to higher symmetry, upon heating. While structural phase transitions have been…
Ohmic Contact Formation Between Metal and AlGaN/GaN Heterostructure via Graphene Insertion
Pil Sung Park, Kongara M. Reddy, Digbijoy N. Nath +3
A simple method for the creation of Ohmic contact to 2-D electron gas (2DEG) in AlGaN/GaN high electron-mobility transistors (HEMTs) using Cr/Graphene layer is demonstrated. A weak…
High Quality, Transferable Graphene Grown on Single Crystal Cu(111) Thin Films on Basal-Plane Sapphire
Kongara M. Reddy, Andrew D. Gledhill, Chun-Hu Chen +2
The current method of growing large-area graphene on Cu surfaces (polycrystalline foils and thin films) and its transfer to arbitrary substrates is technologically attractive. Howe…
