Charge-Induced Second-Harmonic Generation in Bilayer WSe2.
Controlling nonlinear light-matter interaction is important from a fundamental science point of view as well as a basis for future optoelectronic devices. Recent advances in two-dimensional crystalsExpand

Nonlinearity exponents in lightly doped Conducting Polymers
The \textit{I-V} characteristics of four conducting polymer systems like doped polypyrrole (PPy), poly 3,4 ethylene dioxythiophene (PEDOT), polydiacetylene (PDA) and polyaniline (PA) in as manyExpand

Scaling description of non-ohmic direct current conduction in disordered systems
Abstract Complex charge transport mechanisms in disordered systems are often difficult to characterize owing to a dearth of suitable probes. Non-Ohmic response to an applied electric field is howeverExpand

Carbon nanotube field-effect devices with asymmetric electrode configuration by contact geometry
We have studied experimentally the conductive properties of single walled carbon nanotube (SWNT) based field-effect type devices, with different contact geometries at the connecting electrode. TheExpand

Nonlinearity exponents in disordered systems
The effect of an electric field on conduction in a disordered system is an old but largely unsolved problem. Experiments cover an wide variety of systems - amorphous/doped semiconductors, conductingExpand
Charge noise in ballistic multiwalled carbon nanotube transistors
We report an experimental noise study of intermediate sized ballistic semiconducting multiwalled carbon nanotube (MWNT) devices. In this channel limited devices with no significant SchottkyExpand
Scaling of non-Ohmic conduction in strongly correlated systems
A new scaling formalism is used to analyze nonlinearI-V data in the vicinity of metal-insulator transitions (MIT) in five manganite systems. An exponent, called the nonlinearity exponent, and anExpand

Ultra-low noise multiwalled carbon nanotube transistors
We report an experimental noise study of intermediate sized quasi ballistic semiconducting multiwalled carbon nanotube (IS-MWCNT) devices. The noise is two orders of magnitude lower than inExpand

Universal scaling in disordered systems and nonuniversal exponents
The effect of an electric field on conduction in a disordered system is an old but largely unsolved problem. Experiments cover an wide variety of systems - amorphous/doped semiconductors, conductingExpand
