Structural and Electrical Properties of Sputtered HEA Thin Films of CrFeCoNiCu and their Oxidation Studies
High-entropy alloys (HEAs) represent a class of materials that is intensively investigated for a range of possible applications. They generally show a high degree of phase stability by the high entropy while the structure is a random atom position disorder unlike other alloys which can influence...
Exploring functional properties of high entropy oxides
Assembly of Van der Waals Heterostructures for high performance devices
The isolation of graphene has resulted in an increase in the interest in two-dimensional materials. These materials can be selected based on their electronic structure, ranging from semiconductor to insulator. Moreover, the vertical stacking of these materials into heterostructures results in new...

Gamma ray radiation effects on h-BN encapsulated graphene field effect transistors
Formation of continous Si nano-particles based mono-layers on various substrates by e-beam evaporation
Improved Cathode Catalyst Layers for Proton Exchange Membrane Fuel Cells
In this work we show how two different catalyst layer fabrication techniques can improve the PEM fuel cell performance by introducing macro porosities in the layer. In the first technique, a template with 4 μm diameter pillars made using photo lithography is pressed against the cathode side of Gore...
