Size-Dependent Melting Properties of Small Tin Particles: Nanocalorimetric Measurements.
TL;DR: The latent heat of fusion for Sn particles formed by evaporation on inert substrate with radii ranging from 5 to 50 nm has been measured directly using a novel scanning nanocalorimeter and a particle-size-dependent reduction of $\ensuremath{\Delta}{H}_{m}$ has been observed.
Journal ArticleDOI
Growth of semiconducting graphene on palladium.
Soon-Yong Kwon,Cristian V. Ciobanu,V. Petrova,Vivek B. Shenoy,Javier Bareño,Vincent Gambin,Ivan Petrov,Suneel Kodambaka +7 more
TL;DR: In situ scanning tunneling microscopy studies of graphene growth on Pd(111) during ethylene deposition at temperatures between 723 and 1023 K point to the possibility of preparing semiconducting graphene layers for future carbon-based nanoelectronic devices via direct deposition onto strongly interacting substrates.
Journal ArticleDOI
Interface structure in superhard TiN-SiN nanolaminates and nanocomposites: Film growth experiments and ab initio calculations
Lars Hultman,Javier Bareño,Axel Flink,Hans Söderberg,Karin Larsson,V. Petrova,Magnus Odén,Joseph E Greene,Ivan Petrov +8 more
TL;DR: In this article, the nature of the internal interfaces of a nanostructured material is defined by internal interfaces, which are largely unknown, and the interfaces determine the propert...

Moiré superstructures of graphene on faceted nickel islands.
Yuya Murata,V. Petrova,Branden B. Kappes,Abbas Ebnonnasir,Ivan Petrov,Ya-Hong Xie,Cristian V. Ciobanu,Suneel Kodambaka +7 more
TL;DR: The morphology and electronic structure of monolayer graphene grown on the (111) and (110) facets of three-dimensional nickel islands on highly oriented pyrolytic graphite substrate point to the possibility of preparing large-area epitaxial graphene layers even on polycrystalline Ni substrates.
Journal ArticleDOI

E. A. Olson,M. Yu. Efremov,A. T. Kwan,S. L. Lai,V. Petrova,François Schiettekatte,J. T. Warren,Meng Zhang,Leslie H. Allen +8 more
TL;DR: In this paper, a scanning calorimeter was introduced for use with a single solid or liquid sample with a volume down to a few nanoliters, which was demonstrated with the melting of 52 nL of indium, using heating rates from 100 to 1000 K/s.
