Stabilization of Stone-Wales Defects in Metal-supported Graphene
Rob H. Mason, Manuka M. S. Sinharage, Hansika I. Sirikumara +2
The characteristics of graphene-metal interfaces play a decisive role in their electronic, optoelectronic, and mechanical applications. Properties such as charge transfer across th…
Tunable Indirect-Direct Transition of Few-Layer SnSe via Interface Engineering
Hansika I. Sirikumara, Thushari Jayasekera
Tin Selenide (SnSe) is one of the best thermoelectric materials reported to date. The possibility of growing few-layer SnSe helped boost the interest in this long-known, earth abun…
Viable route towards large-area two dimensional MoS2 using magnetron sputtering
Hassana Samassekou, Asma Alkabsh, Milinda Wasala +8
Structural, interfacial, optical, and transport properties of large-area MoS2 ultra-thin films on BN-buffered silicon substrates fabricated using magnetron sputtering are investiga…
Unexpected Structures for Intercalation of Sodium in Epitaxial Graphene-SiC Interfaces
Andreas Sandin, Thushari Jayasekera, J. E. +4
We show using scanning tunneling microscopy, spectroscopy, and ab initio calculations that several intercalation structures exist for Na in epitaxial graphene on SiC(0001). Interca…
Quantum coherent negative bend resistance in InSb mesoscopic structures
N. Goel, T. Jayasekera, K. Mullen +4
Transport measurements were made on four-terminal devices fabricated from InSb/Al_xIn_(1-x)Sb quantum well structures at temperatures from 1.5 to 300K. Negative bend resistance, wh…
Evaporative Cooling in Semiconductor Devices
Thushari Jayasekera, Kieran Mullen, Michael A. Morrison
We discuss the theory of cooling electrons in solid-state devices via ``evaporative emission.'' Our model is based on filtering electron subbands in a quantum-wire device. When inc…
