Layer-by-layer hybrid chemical doping for high transmittance uniformity in graphene-polymer flexible transparent conductive nanocomposite.
Chandan Biswas,Chandan Biswas,İdris Candan,İdris Candan,Yazeed Alaskar,Yazeed Alaskar,Hussam Qasem,Wei Zhang,Adam Z. Stieg,Ya-Hong Xie,Kang L. Wang +10 more
TL;DR: A unique hybrid chemical doping method is shown that results in high transmittance uniformity in a layered graphene-polymer nanocomposite with suppressed defect-induced carrier scattering in a traditional transparent conducting film.
Journal ArticleDOI
A Study of Vertical Transport through Graphene toward Control of Quantum Tunneling
Xiaodan Zhu,Sidong Lei,Shin Hung Tsai,Xiang Zhang,Jun Liu,Gen Yin,Min Tang,Carlos M. Torres,Aryan Navabi,Zehua Jin,Shiao-Po Tsai,Hussam Qasem,Yong Wang,Robert Vajtai,Roger K. Lake,Pulickel M. Ajayan,Kang L. Wang +16 more
TL;DR: A new model on the quantum capacitance's effect on vertical Tunneling is developed to further elucidate the role of graphene in modulating the tunneling process, and may serve as a general guideline for the design and analysis of vdW vertical tunneling devices and heterostructures.
Journal ArticleDOI
Dual-mode Operation of 2D Material-Base Hot Electron Transistors
Yann Wen Lan,Carlos M. Torres,Xiaodan Zhu,Hussam Qasem,James R. Adleman,Mitchell B. Lerner,Shin Hung Tsai,Yumeng Shi,Lain-Jong Li,Wen Kuan Yeh,Kang L. Wang +10 more
TL;DR: This work demonstrates a novel functionality, specifically a dual-mode operation, in 2D material-base hot electron transistors that can operate in either a hot-electron or a reverse-current dominating mode depending upon the particular polarity of VCB.
Journal ArticleDOI
Engineering Red-Enhanced and Biocompatible Upconversion Nanoparticles
Masfer Alkahtani,Najla Alsofyani,Anfal Alfahd,Anas A. Almuqhim,Fahad A. Almughem,Abdullah A. Alshehri,Hussam Qasem,Philip R. Hemmer +7 more
TL;DR: In this article, a core-shell-shell (CSS) structure was proposed to improve the brightness of small upconversion nanoparticles by optimizing dopant concentrations and utilizing the addition of inert shells to avoid surface quenching effects.
