Ultrafast all-optical switch using carbon nanotube polymer composites
Yiping Zhao,Yuchuan Chen,Xi-Cheng Zhang,Nachiket R. Raravikar,Pulickel M. Ajayan,Toh-Ming Lu,Gwo-Ching Wang,Linda S. Schadler Feist +7 more
TL;DR: An ultrafast all-optical nonlinear switch has been proposed in this article with a switching speed of less than 1 picosecond for light with a wavelength of about 1.55 micrometers.
Journal ArticleDOI
Controlled assembly of Ag nanoparticles and carbon nanotube hybrid structures for biosensing.
TL;DR: The proposed method can be used to decorate and/or assemble metal nanoparticles or fractal patterns along SWCNTs with different novel metals such as gold, silver, and copper and can be exploited in various sensitive applications for fundamental research and nanotechnology.
Journal ArticleDOI
Spatially Resolved Photoexcited Charge-Carrier Dynamics in Phase-Engineered Monolayer MoS2
Hisato Yamaguchi,Jean-Christophe Blancon,Rajesh Kappera,Sidong Lei,Sina Najmaei,Benjamin D. Mangum,Gautam Gupta,Pulickel M. Ajayan,Jun Lou,Manish Chhowalla,Jared Crochet,Aditya D. Mohite +11 more
TL;DR: In this article, the authors investigated the transport properties of chemical vapor deposition (CVD) grown monolayer molybdenum disulfide (MoS2) under photoexcitation using correlated scanning photocurrent microscopy and photoluminescence imaging.
Journal ArticleDOI
Metal Immiscibility Route to Synthesis of Ultrathin Carbides, Borides, and Nitrides.
Zixing Wang,Vidya Kochat,Prafull Pandey,Sanjay Kashyap,Sanjay Kashyap,Soham Chattopadhyay,Atanu Samanta,Suman Sarkar,Praveena Manimunda,Xiang Zhang,S. A. Syed Asif,Abhisek K. Singh,Kamanio Chattopadhyay,Chandra Sekhar Tiwary,Pulickel M. Ajayan +14 more
TL;DR: These ultrathin materials have good interface attachment with Cu, improving the scratch resistance and oxidation resistance of Cu, and can be extended to other metals to synthesize metal carbide, boride, and nitride coatings.
Journal ArticleDOI
Aligned Carbon Nanotube Stationary Phases for Electrochromatographic Chip Separations
Shubhodeep Goswami,Navdeep Bajwa,Prashanth Asuri,Lijie Ci,Pulickel M. Ajayan,Steven M. Cramer +5 more
TL;DR: In this paper, a microfluidic electrochromatographic chip device using patterned vertically aligned carbon nanotubes as the stationary phase material was developed using a solid phase Fe-Al catalyst and a vapor deposited ferrocene catalyst.
