We observe that the Fuchs–Sondheimer model works for thickness-dependent thermal conductivity of MoS<sub>2</sub> down to 10 nm in thickness at room temperature, yielding a phonon mean free path 17 bulk.
Abstract The recent challenges for improving the operation speed of nanoelectronics have motivated research on manipulating light in on-chip integrated circuits. Hybrid plasmonic waveguides with low-dimensional semiconductors, including quantum dots and wells, are a promising platform realizing sub-diffraction limited optical components. Meanwhile, two-dimensional transition metal dichalcogenides (TMDs) received broad interest optoelectronics owing to tightly bound excitons at room...

Electrochemical doping of the n-type polymer poly(benzimidazobenzophenanthroline) (BBL) in contact with ionic liquids reveals a peak drain current (ID) vs gate voltage (VG) behavior, i.e., conductivity versus electron density. The is related to simultaneously acquired current-gate (IG-VG) charging curves that are integrated yield total charge accumulation. IG-VG traces reveal three separate redox events upon BBL can be correlated ID-VG behavior. We assign first broad accumulation mobile...
III–V semiconductors are considered ideal materials for optoelectronic applications due to their direct bandgap and wide tunable range of energy. However, devices based on have been plagued by significant surface recombination imperfect bonding. Meanwhile, 2D transition metal dichalcogenides (TMDs) exhibit unique electrical properties, including a dangling bond‐free surface, which has led extensive research into potential electronic applications. optical such as photodetectors utilizing...

Reported here is the low-temperature growth of multiple-stack high-density ZnO nanoflower/nanorod structures on polyethylene naphthalate (PEN) substrates derived from surface modification seed layers using an atmospheric-pressure plasma jet (APPJ) treatment. The treatment could provide several advantages to structures: (i) wettability changes hydrophobic hydrophilic, resulting in higher energies for nanoflowers, (ii) nucleation sites increase due increased roughness caused by etching, and...
