Development of 3D tomosynthesis technique for nondestructive technology application using vertically aligned carbon nanotube-based high-resolution cold cathode electron beam

Autor: Jaydip Sawant, Yi Yin Yu, Ketan Bhotkar, Hyun-Jung Jung, Gi Joon Nam, Kyu Chang Park

Publikováno v: Journal of Vacuum Science & Technology B. 41:033201

Nondestructive technology (NDT) is the most popular method for detecting defects inside an object without harming it. A 3D tomography algorithm toolbox and an x-ray imaging system are the essential components of NDT. We fabricated a high-resolution c

Novel technique to control the focal spot size using carbon nanotube based cold cathode electron beam (C-beam) architecture

Autor: Ketan Bhotkar, Yi Yin Yu, Jaydip Sawant, Ravindra Patil, Kyu Chang Park

Publikováno v: Journal of Vacuum Science & Technology B. 41:023202

This article discusses the development of a cold cathode electron beam (C-beam) based on vertically aligned carbon nanotubes (VACNTs) and the optimization of field emission (FE) from C-beam architecture design. The characteristics of the electron bea

Tellurium-free thermoelectrics: Improved thermoelectric performance of n-type Bi 2 Se 3 having multiscale hierarchical architecture

Autor: Ajay Singh, Shovit Bhattacharya, Ketan Bhotkar, K. P. Muthe, Anil Bohra, K.N. Meshram, Pramod Bhatt, Ranita Basu, Kunjal Shah, Saloni Sharma, Anil Kumar Chauhan, S. C. Gadkari, Ranu Bhatt, Sajid Ahmad, Dinesh K. Aswal, Anjan Debnath

Publikováno v: Energy Conversion and Management. 145:415-424

Presence of Hierarchical length scale defect architecture in hot-pressed Bi2Se3 has resulted into a significantly reduced thermal conductivity value of ∼0.7 W/mK and yielded a maximum figure-of-merit value of ∼0.96 at 370K.
