Metal Oxide-based Gas Sensor Array for the VOCs Analysis in Complex Mixtures using Machine Learning
Shivam Singh, Sajana S, Poornima +4
Detection of Volatile Organic Compounds (VOCs) from the breath is becoming a viable route for the early detection of diseases non-invasively. This paper presents a sensor array wit…
CVD Growth of Tin Selenide Thin Films for Optoelectronic Applications
Shivam Tyagi, Shubham Yadav, Vaibhav Wani +4
Tin Selenide (SnSe) thin films were grown onto glass and alumina substrates by Chemical Vapor Deposition (CVD) method. The structural, micro-structural and morphological characteri…
Coexistence of Multiple Magnetic Interactions in Oxygen Deficient V2O5 Nanoparticles
Tathagata Sarkar, Soumya Biswas, Sonali Kakkar +3
This paper reports on the spin glass-like coexistence of competing magnetic orders in oxygen-deficient V2O5 nanoparticles having a broad size distribution. X-ray photoelectron spec…
Protonic Conduction Induced Selective Room Temperature Hydrogen Response in ZnO/NiO Heterojunction Surfaces
Kusuma Urs MB, Vinayak B Kamble
In this paper we show that the ionic conduction through surface chemisorbed ambient moisture leads to the remarkably high room temperature selective response towards hydrogen gas.…
Selective Enhancement in Phonon Scattering leads to High Thermoelectric Figure of Merit in ZnO -- Graphene Oxide Core-shell Nanohybrids
Soumya Biswas, Saurabh Singh, Shubham Singh +5
ZnO is a promising candidate as an environment friendly thermoelectric (TE) material. However, the poor TE figure of merit (zT) needs to be addressed to achieve significant TE effi…
Thickness induced metal to insulator charge transport and unusual hydrogen response in granular palladium nanofilms
Dharmendra K. Singh, Praveen S. G., Adithya Jayakumar +4
This work reports a systematic study of the evolution of charge transport mechanism in granular ultra-thin films of palladium of thickness varying between 6nm and 2nm. While the fi…
Proof-of-concept thermoelectric oxygen sensor exploiting oxygen mobility of GdBaCo2O5+δ
Soumya Biswas, Madhujith M K, Vinayak Kamble
In this paper, we demonstrate a proof-of-concept oxygen sensor based on the thermoelectric principle using polycrystalline where 0.45<<0.55 (GDCO). The lattice…
Simple, Reversible Gradient Seebeck Coefficient Measurement System for 300-600K
Soumya Biswas, Aditya S Dutt, Nirmal Sabastian +1
An in-house Seebeck coefficient measurement system has been developed which can measure the thermoemf (Seebeck coefficient) of the sample, under large temperature difference, in th…
