Epitaxial Growth of Ultra-smooth -NbN Thin Films on TiN-Buffered Sapphire by Room-Temperature Sputtering
Swagata Bhunia, Aakash Shandilya, Sounak Samanta +7
The phase of Niobium Nitride (NbN) is a promising superconducting material, which is chemically stable and shares lattice compatibility with conventional III-Nitride semicondu…
Beyond 5 GHz excitation of a ZnO-based high-overtone bulk acoustic resonator on SiC substrate
Padmalochan Panda, Soumyadip Chatterjee, Siddharth Tallur +1
This work reports on the fabrication and characterization of an Au/ZnO/Pt-based high-overtone bulk acoustic resonator (HBAR) on SiC substrates. We evaluate its microwave characteri…
Spectroscopic Signature of Local Alloy Fluctuations in InGaN/GaN Multi-Quantum-Disk Light Emitting Diode Heterostructures and Its Impact on the Optical Performance
Soumyadip Chatterjee, Subhranshu Sekhar Sahu, Kanchan Singh Rana +3
Inhomogeneity-governed carrier localization has been investigated in three sets of InGaN/GaN multi-quantum-disk light-emitting diode (LED) structures grown by plasma-assisted molec…
Unraveling the Origin of Mysterious Luminescence peak at 3.45 eV in GaN Nanowires
Swagata Bhunia, Soumyadip Chatterjee, Ritam Sarkar +3
The demand for GaN Nanowires (NWs)-based optoelectronic devices has rapidly increased over the past few years due to its superior crystalline quality compare to their planar counte…
