TL;DR: This work introduces a growth mode that enables direct writing of single-crystalline III–V's on amorphous substrates, thus further expanding their utility for various applications and presenting an important advance towards universal integration of III– V's on application-specific substrates by direct growth.
Journal ArticleDOI
Theory of thin-film-mediated exfoliation of van der Waals bonded layered materials
Haoye Sun,Eric W. Sirott,James P. Mastandrea,James P. Mastandrea,Hannah M. Gramling,Yuzhi Zhou,Max Poschmann,Hayden Taylor,Joel W. Ager,Joel W. Ager,Daryl C. Chrzan,Daryl C. Chrzan +11 more
TL;DR: In this article, the influence of epitaxially induced biaxial strain on the exfoliated layer and how this impacts monolayer selectivity during exfoliation was explored using atomic scale total energy calculations.
Journal ArticleDOI
Measuring the edge recombination velocity of monolayer semiconductors
Peida Zhao,Matin Amani,Der Hsien Lien,Geun Ho Ahn,Daisuke Kiriya,James P. Mastandrea,Joel W. Ager,Eli Yablonovitch,Daryl C. Chrzan,Ali Javey +9 more
TL;DR: This work quantifies the non-radiative recombination edge effects in monolayer semiconductors, while simultaneously establishing a practical characterization technique towards experimental explorations of edge passivation methods for 2D materials.
