Terahertz All-Optical Modulation in a Silicon-Polymer Hybrid System
Michael Hochberg,Tom Baehr-Jones,Guangxi Wang,Michael Shearn,Katherine Harvard,Jingdong Liu,Baoquan Chen,Zhengwei Shi,Rhys Lawson,Phil Sullivan,Alex K.-Y. Jen,Larry R. Dalton,Axel Scherer +12 more
TL;DR: In this article, the authors have demonstrated intensity modulation of light with light in a silicon-polymer integrated waveguide device, based on the all-optical Kerr effect -the same ultrafast effect used in four-wave mixing.
Journal ArticleDOI
Divalent osmium complexes: synthesis, characterization, strong red phosphorescence, and electrophosphorescence.
Brenden Carlson,Gregory D. Phelan,Werner Kaminsky,Larry R. Dalton,Xuezhong Jiang,Sen Liu,Alex K.-Y. Jen +6 more
TL;DR: New divalent osmium complexes that feature strong red metal-to-ligand-charge-transfer (MLCT) phosphorescence and electrophosphorescence and 2-tert-butylphenyl-5-biphenyl-1,3,4-oxadiazole (PBD) are reported.
Journal ArticleDOI
Highly Efficient and Thermally Stable Electro‐Optical Dendrimers for Photonics
Hong Ma,Shili Liu,Jingdong Luo,S. Suresh,Lu Liu,Seok Ho Kang,Marnie Haller,Takafumi Sassa,Larry R. Dalton,Alex K.-Y. Jen +9 more
TL;DR: In this paper, a review of electro-optical (EO) dendrimers is presented, and a double-end functionalization of a three-dimensional phenyl-tetracyanobutadienyl (Ph-TCBD)-containing nonlinear optical (NLO) chromophore with thermally crosslinkable trifluorovinylether-containing dendrons is presented.
Journal ArticleDOI
Suppressed Charge Recombination in Inverted Organic Photovoltaics via Enhanced Charge Extraction by Using a Conductive Fullerene Electron Transport Layer
Chang-Zhi Li,Chih Yu Chang,Yue Zang,Huanxin Ju,Huanxin Ju,Chu-Chen Chueh,Po-Wei Liang,Namchul Cho,David S. Ginger,Alex K.-Y. Jen +9 more
TL;DR: Transient photovoltage (TPV) measurements are used to shed light on how these conductive ETLs help suppress charge recombination in solar cells.
Journal ArticleDOI
2D metal-organic framework for stable perovskite solar cells with minimized lead leakage
Shengfan Wu,Zhen Li,Mu-Qing Li,Mu-Qing Li,Yingxue Diao,Francis Lin,Tiantian Liu,Jie Zhang,Peter Tieu,Wenpei Gao,Feng Qi,Xiaoqing Pan,Zhengtao Xu,Zonglong Zhu,Alex K.-Y. Jen,Alex K.-Y. Jen +15 more
TL;DR: A thiol-functionalized 2D conjugated metal–organic framework as an electron-extraction layer at the perovskite/cathode interface enables the realization of highly stable perovSKite solar cells with minimized lead ion leakage.
