Charge-depletion-enhanced WSe2 quantum emitters on gold nanogap arrays with near-unity quantum efficiency by Cai, Hongbing, Rasmita, Abdullah, He, Ruihua, Zhang, Zhaowei, Tan, Qinghai, Chen, Disheng, Wang, Naizhou, Mu, Zhao, Eng, John J. H., She, Yongzhi, Pan, Nan, Wang, Qian, Dong, Zhaogang, Wang, Xiaoping, Wang, Juan, Miao, Yansong, Singh, Ranjan, Qiu, Cheng-Wei, Liu, Xiaogang, Gao, Weibo

“…In this condition, for site-controlled SPEs in WSe2 coupled to gold nanogaps, the SPE transition quantum efficiency after gating is increased to 76.4 ± 14.6% on average, with some SPEs reaching near-unity (more than 90%) quantum efficiency. This study provides a new approach for tuning SPEs with an applied gate voltage and motivates further theoretical and experimental studies of SPE enhancement on vertically aligned nanogaps.…”

A dual-functional benzobisthiadiazole derivative as an effective theranostic agent for near-infrared photoacoustic imaging and photothermal therapy by Huang, Shuo, Upputuri, Paul Kumar, Liu, Hui, Pramanik, Manojit, Wang, Mingfeng

“…Herein, we report a theranostic agent based on a narrow-­‐bandgap small molecule, benzo[1,2-c;4,5-c’]bis[1,2,5]thiadiazole-4,7-bis(9,9-dioctyl-9H-­fluoren-­2-yl)thiophene (denoted as BBT-2FT), with strong absorption of near infrared (NIR) light. Colloidal nanoparticles composed of BBT­‐2FT show photoacoustic signal intensity 10 times higher than that of blood, and high photothermal conversion efficiency (η=40%) under irradiation of 800-nm laser light that kills over 90% HeLa cells in 10 mins.…”

Three-dimensional modeling of near-field beam profiles from grating couplers using a deep neural network by Lim, Yu Dian, Tan, Chuan Seng

“…As the formfactor of ion traps reduces, the ion-trapping height decreases, and may unavoidably fall into the reactive near-field region of SiPh gratings. In this study, a deep neural network (DNN) modeling technique is developed as a rapid alternative to generate reactive near-field beam profiles of light coupled from SiPh gratings, as compared to the conventional finite-difference time-domain (FDTD) technique. …”
