Journal ArticleDOI
Selective ionic transport through tunable subnanometer pores in single-layer graphene membranes.
Sean C. O'Hern,Michael S. H. Boutilier,Juan Carlos Idrobo,Yi Song,Jing Kong,Tahar Laoui,Muataz Ali Atieh,Rohit Karnik +7 more
TL;DR: The ability to tune the selectivity of graphene through controlled generation of subnanometer pores addresses a significant challenge in the development of advanced nanoporous graphene membranes for nanofiltration, desalination, gas separation, and other applications.
Journal ArticleDOI
Electrically Tunable Metasurface Perfect Absorbers for Ultrathin Mid-Infrared Optical Modulators
TL;DR: It is shown that a widely tunable metasurface composed of optical antennas on graphene can be incorporated into a subwavelength-thick optical cavity to create an electrically tunable perfect absorber.
Journal ArticleDOI
Broad electrical tuning of graphene-loaded plasmonic antennas.
TL;DR: In situ control of antennas using graphene as an electrically tunable load in the nanoscale antenna gap is demonstrated and shows that combining graphene with metallic nanostructures provides a route to electrically Tunable optical and optoelectronic devices.
Journal ArticleDOI
Role of interfacial oxide in high-efficiency graphene-silicon Schottky barrier solar cells.
Yi Song,Xinming Li,Charles Mackin,Xu Zhang,Wenjing Fang,Tomas Palacios,Hongwei Zhu,Jing Kong +7 more
TL;DR: It is shown that the native oxide on the silicon presents a transport barrier for photogenerated holes and causes recombination current, which is responsible for causing the kink, and a simple semiconductor physics model is proposed that qualitatively captures the effect.
Journal ArticleDOI
Remote epitaxy through graphene enables two-dimensional material-based layer transfer
Yunjo Kim,Samuel S. Cruz,Kyusang Lee,Babatunde Alawode,Chanyeol Choi,Yi Song,Jared M. Johnson,Christopher Heidelberger,Wei Kong,Shinhyun Choi,Kuan Qiao,Ibraheem Almansouri,Ibraheem Almansouri,Eugene A. Fitzgerald,Jing Kong,Alexie M. Kolpak,Jinwoo Hwang,Jeehwan Kim +17 more
TL;DR: It is shown that the weak van der Waals potential of graphene cannot completely screen the stronger potential field of many substrates, which enables epitaxial growth to occur despite its presence, and is also applicable to InP and GaP.
