ZnO/Ag/ZnO multilayer films for the application of a very low resistance transparent electrode
TL;DR: Transparent conductive ZnO/Ag/ZnO multilayer electrodes having much lower electrical resistance than the widely used transparent electrodes were prepared by simultaneous RF magnetron sputtering of ZnOs and DC magnetron stuttering of Ag as mentioned in this paper.
Journal ArticleDOI
Micro-Raman and XPS studies of pure ZnO ceramics
J. Das,Sangram K. Pradhan,Diptiranjan Sahu,Dilip Kumar Mishra,Sachindra Nath Sarangi,B.B. Nayak,Sarika Verma,B. K. Roul +7 more
TL;DR: In the absence of any magnetic impurity, the cause of room temperature ferromagnetic signal in the undoped system is attributed to various kinds of native defects such as oxygen vacancies (V O ) or zinc interstitials (I Zn ) and their clusters created inside the bulk ceramics during heating by slow step sintering schedule as mentioned in this paper.
Journal ArticleDOI
High quality transparent conductive ZnO/Ag/ZnO multilayer films deposited at room temperature
Diptiranjan Sahu,Jow-Lay Huang +1 more
TL;DR: In this paper, a multilayer transparent electrode with high optical transmittance and high electrical resistance was fabricated by simultaneous DC and RF magnetron sputtering, having resistance as low as 3 Ω/sq and high optical transmission power of 90% at room temperature.
Journal ArticleDOI
Investigation of conductive and transparent Al-doped ZnO/Ag/Al-doped ZnO multilayer coatings by electron beam evaporation
TL;DR: In this paper, the optical and electrical performances of multilayer Al-doped ZnO (AZO) and Ag/AZO multilayers were investigated, which resulted with low sheet resistance of 7.7 and transmittance of 85% respectively.
Journal ArticleDOI
Effect of holmium substitution for the improvement of multiferroic properties of BiFeO3
Sangram K. Pradhan,J. Das,P.P. Rout,V. Mohanta,S.K. Das,S. Samantray,Diptiranjan Sahu,Jow-Lay Huang,Sarika Verma,B. K. Roul +9 more
TL;DR: In this paper, the multiferroic properties of Ho substituted BiFeO 3 (Bi 1− x Ho x FeO 3 ) ceramics were investigated and it was shown that Ho substitution at Bi site is likely to suppress the spiral spin modulation and at the same time increase the canting angle.
