Optothermally Induced Active and Chiral Motion of the Colloidal Structures
Rahul Chand, Ashutosh Shukla, Sneha Boby +1
Artificial soft matter systems have appeared as important tools to harness mechanical motion for microscale manipulation. Typically, this motion is driven either by the external fi…
Synchronized motion of gold nanoparticles in an optothermal trap
Ashutosh Shukla, Rahul Chand, Sneha Boby +1
Optical tweezers have revolutionized particle manipulation at the micro- and nanoscale, playing a critical role in fields such as plasmonics, biophysics, and nanotechnology. While…
Optothermal Revolution: Colloids in an Optical Ring Trap
Rahul Chand, Ashutosh Shukla, G V Pavan Kumar
Directional motion is commonly observed in various living active systems, such as bacterial colonies moving through confined environments. In these systems, the dynamics arise from…
Evanescent Optothermoelectric Trapping: Deeper Potentials at a Largescale
Chaudhary Eksha Rani, Rahul Chand, Ashutosh Shukla +1
Surface plasmons (SP) and their mediated effects have been widely used to manipulate micro- and nanoscale objects of dielectric and metallic nature. In this work, we show how SP ex…
Probing the Relationship between Defects and Enhanced Mobility in MoS2 Monolayers Grown by Mo Foil
Sudipta Majumder, Vaibhav Walve, Rahul Chand +5
Atomic vacancies, such as chalcogen vacancies in 2D TMDs, are important in changing the host material's electronic structure and transport properties. We present a straightforward…
