Journal ArticleDOI
Field-Effect Transistors Built from All Two-Dimensional Material Components
Tania Roy,Mahmut Tosun,Mahmut Tosun,Jeong Seuk Kang,Jeong Seuk Kang,Angada B. Sachid,Sujay B. Desai,Sujay B. Desai,Mark Hettick,Mark Hettick,Chenming Hu,Ali Javey,Ali Javey +12 more
TL;DR: In this work, all interfaces are based on van der Waals bonding, presenting a unique device architecture where crystalline, layered materials with atomically uniform thicknesses are stacked on demand, without the lattice parameter constraints, demonstrating the promise of using an all-layered material system for future electronic applications.
Journal ArticleDOI
Efficient silicon solar cells with dopant-free asymmetric heterocontacts
James Bullock,Mark Hettick,Mark Hettick,Jonas Geissbühler,Alison J. Ong,Alison J. Ong,Thomas Allen,Carolin M. Sutter-Fella,Carolin M. Sutter-Fella,Teresa Chen,Hiroki Ota,Hiroki Ota,Ethan W. Schaler,Stefaan De Wolf,Christophe Ballif,Andres Cuevas,Ali Javey,Ali Javey +17 more
TL;DR: In this paper, the dopant-free electron and hole carrier-selective heterocontacts using alkali metal fluorides and metal oxides, respectively, in combination with passivating intrinsic amorphous silicon interlayers, were successfully developed and implemented.
Journal ArticleDOI
Gold-Mediated Exfoliation of Ultralarge Optoelectronically-Perfect Monolayers
Sujay B. Desai,Sujay B. Desai,Surabhi R. Madhvapathy,Surabhi R. Madhvapathy,Matin Amani,Matin Amani,Daisuke Kiriya,Daisuke Kiriya,Mark Hettick,Mark Hettick,Mahmut Tosun,Mahmut Tosun,Yuzhi Zhou,Madan Dubey,Joel W. Ager,Joel W. Ager,Daryl C. Chrzan,Daryl C. Chrzan,Ali Javey,Ali Javey +19 more
TL;DR: Electrical, optical, and X-ray photo-electron spectroscopy characterization show that the quality of the gold-exfoliated flakes is similar to that of tape-exporiated flakes, which allow manufacturing of large-area mono-layer transition metal dichalcogenide electronics.
Journal ArticleDOI
