Dai, Zijie; Manjappa, Manukumara; Yang, Yunkun; Tan, Thomas Cai Wei; Qiang, Bo; Han, Song; Wong, Liang Jie; Xiu, Faxian; Liu, Weiwei; Singh, Ranjan, 2021, "Replication Data for: High Mobility 3D Dirac Semimetal (Cd3As2) for Ultrafast Photoactive Terahertz Photonics", https://doi.org/10.21979/N9/G5GIEN, DR-NTU (Data), V1
The Dirac semimetal cadmium arsenide (Cd3As2), a 3D electronic analog of graphene, has sparked renewed research interests for its novel topological phases and excellent optoelectronic properties. The gapless nature of its 3D electronic band facilitates strong optical nonlinearity...

Gupta, Manoj; Singh, Ranjan, 2021, "Replication Data for: Terahertz Sensing with Optimized Q/Veff Metasurface Cavities", https://doi.org/10.21979/N9/SRDC9A, DR-NTU (Data), V1, UNF:6:1U/9Po6a5ClppS0honp8Jw== [fileUNF]
Confinement of electromagnetic radiation in a subwavelength cavity is an important platform for strong light–matter interaction as it enables efficient design of photonic switches, modulators, and ultrasensitive sensors. Metallic metasurfaces consist of an array of planar cavitie...
