Thermal conductivity and electrical transport properties of double-A-layer MAX phase Mo2Ga2C

open access: yesMaterials Research Letters, 2020
The present study reports the thermal conductivity and electrical transport properties of Mo2Ga2C, which is the first member of double-A-layer MAX phases. Dense bulk samples of Mo2Ga2C were prepared by vacuum hot pressing.

Emerging properties of non-crystalline phases of graphene and boron nitride based materials

open access: yesNano Materials Science, 2022
We review recent developments on the synthesis and properties of two-dimensional materials which, although being mainly of an sp2 bonding character, exhibit highly disordered, non-uniform and structurally random morphologies.

Fractional composition of large crystallite grains: a unique microstructural parameter to explain conduction behavior in single phase undoped microcrystalline silicon [PDF]

open access: yes, 2007
We have studied the dark conductivity of a broad microstructural range of plasma deposited single phase undoped microcrystalline silicon films in a wide temperature range (15 - 450K) to identify the possible transport mechanisms and the interrelationship

Fingerprints of a size-dependent crossover in the dimensionality of electronic conduction in Au-seeded Ge nanowires

open access: yesBeilstein Journal of Nanotechnology, 2016
We studied the electrical transport properties of Au-seeded germanium nanowires with radii ranging from 11 to 80 nm at ambient conditions. We found a non-trivial dependence of the electrical conductivity, mobility and carrier density on the radius size ...
