Graphene based functional devices: A short review
Rong Wang, Xingang Ren, Ze Yan +3
Graphene is an ideal 2D material system bridging electronic and photonic devices. It also breaks the fundamental speed and size limits by electronics and photonics, respectively. G…
Generation of Orbital Angular Momentum by a Point Defect in Photonic Crystals
Menglin L. N. Chen, Li Jun Jiang, Wei E. I. Sha
As an attractive degree of freedom in electromagnetic (EM) waves, the orbital angular momentum (OAM) enables infinite communication channels for both classical and quantum communic…
The Effects of Interfacial Recombination and Injection Barrier on the Electrical Characteristics of Perovskite Solar Cells
Lin Xing Shi, Zi Shuai Wang, Zengguang Huang +3
Charge carrier recombination in the perovskite solar cells (PSCs) has a deep influence on the electrical performance, such as open circuit voltage, short circuit current, fill fact…
Electrically Tunable Polarizer Based on Graphene-loaded Plasmonic Cross Antenna
Yuwei Qin, Xiaoyan Y. Z. Xiong, Wei E. I. Sha +1
The unique gate-voltage dependent optical properties of graphene make it a promising electrically-tunable plasmonic material. In this work, we proposed in-situ control of the polar…
Orbital Angular Momentum Generation and Detection by Geometric-Phase Based Metasurfaces
Menglin L. N. Chen, Li Jun Jiang, Wei E. I. Sha
We present a comprehensive review on the geometric-phase based metasurfaces for orbital angular momentum(OAM) generation and detection. These metasurfaces manipulate the electromag…
Quantifying Efficiency Loss of Perovskite Solar Cells by a Modified Detailed Balance Model
Wei E. I. Sha, Hong Zhang, Zi Shuai Wang +5
A modified detailed balance model is built to understand and quantify efficiency loss of perovskite solar cells. The modified model captures the light-absorption dependent short-ci…
