Journal ArticleDOI
Polarization-resolved black phosphorus/molybdenum disulfide mid-wave infrared photodiodes with high detectivity at room temperature
James Bullock,James Bullock,Matin Amani,Matin Amani,Joy Cho,Joy Cho,Yu Ze Chen,Geun Ho Ahn,Geun Ho Ahn,Valerio Adinolfi,Valerio Adinolfi,Vivek Raj Shrestha,Yang Gao,Kenneth B. Crozier,Yu-Lun Chueh,Ali Javey,Ali Javey +16 more
TL;DR: In this article, a bias-selectable polarization-resolved photodetector that operates without the need for external optics was proposed. But the performance of the two-terminal device was not evaluated.
Journal ArticleDOI

Matin Amani,Matin Amani,Chaoliang Tan,Chaoliang Tan,George Zhang,George Zhang,Chunsong Zhao,Chunsong Zhao,James Bullock,James Bullock,Xiaohui Song,Xiaohui Song,Hyungjin Kim,Hyungjin Kim,Vivek Raj Shrestha,Yang Gao,Kenneth B. Crozier,Mary Scott,Mary Scott,Ali Javey,Ali Javey +20 more
TL;DR: In this paper, a solution-synthesized and air-stable quasi-2D tellurium (Te) nanoflakes for short-wave infrared (SWIR) photodetectors were reported.
Journal ArticleDOI
Aluminum plasmonics based highly transmissive polarization-independent subtractive color filters exploiting a nanopatch array
TL;DR: These subtractive color filters have twice the photon throughput of additive counterparts, ultimately providing elevated optical transmission and thus stronger color signals and are anticipated to be diversely applied to digital display, digital imaging, color printing, and sensing.
Journal ArticleDOI
Structural Color Filters Enabled by a Dielectric Metasurface Incorporating Hydrogenated Amorphous Silicon Nanodisks.
Chul-Soon Park,Vivek Raj Shrestha,Vivek Raj Shrestha,Wenjing Yue,Song Gao,Sang-Shin Lee,Eun-Soo Kim,Duk-Yong Choi +7 more
TL;DR: This work proposes and realizes highly efficient structural color filters based on a dielectric metasurface exploiting hydrogenated amorphous silicon (a-Si:H), known to be lossy in the visible regime.
Journal ArticleDOI
Omnidirectional color filters capitalizing on a nano-resonator of Ag-TiO2-Ag integrated with a phase compensating dielectric overlay
TL;DR: A highly efficient omnidirectional color filter that takes advantage of an Ag-TiO2-Ag nano-resonator integrated with a phase-compensating TiO2 overlay and a dielectric overlay is presented.
