Journal ArticleDOI
Scaling description of non-ohmic direct current conduction in disordered systems
TL;DR: In this paper, the electrical transport properties of several disordered systems including composites, amorphous/doped semiconductors, conducting polymers and manganites (both in single crystal and poly-crystalline phase) are highlighted from the standpoint of non-Ohmic direct current conduction.
Journal ArticleDOI
Tetragonal graphene nanodot as carbon monoxide gas sensor and current rectification device
TL;DR: In this paper, the utilities of non-toxic boron (B)-nitrogen (N) pair substitution on tetragonal graphene (T-graphene/TG) nanodot in CO gas sensing were explored.
Journal ArticleDOI
A real-space study of random extended defects in solids: Application to disordered Stone–Wales defects in graphene
Suman Chowdhury,Santu Baidya,Dhani Nafday,Soumyajyoti Halder,Mukul Kabir,Biplab Sanyal,Tanusri Saha-Dasgupta,Debnarayan Jana,Abhijit Mookerjee +8 more
TL;DR: In this paper, a parameter free real space method for the study of disordered extended defects in solids is proposed. But the technique is general enough to be applied to a whole class of systems with lattice translational symmetry broken not only locally but by extended defects and defect clusters.
Journal ArticleDOI
Clustered vacancies in ZnO: chemical aspects and consequences on physical properties
S. Pal,Narendar Gogurla,Avishek Das,Shib Shankar Singha,Pravin Kumar,D. Kanjilal,Achintya Singha,Sanatan Chattopadhyay,Debnarayan Jana,Anindya Sarkar +9 more
TL;DR: In this paper, 1.2 MeV Ar ion beam is used to incorporate defects in granular ZnO. The evolution of defective state with irradiation fluence 1 x 10^14 and 1 × 10^16 ions/cm2 has been monitored using XPS, PL and Raman spectroscopic study.
Journal ArticleDOI
Low temperature photoluminescence from disordered granular ZnO
TL;DR: In this article, an in-depth study using low temperature PL and room temperature Raman spectroscopy was conducted to shed light on the widely discussed issue of defects and photoluminescence (PL) from ZnO material.
