Iridium-doping as a strategy to realize visible light absorption and p-type behavior in BaTiO3
Sujana Chandrappa, Simon Joyson Galbao, P S Sankara Rama Krishnan +8
BaTiO3 is typically a strong n-type material with tuneable optoelectronic properties via doping and controlling the synthesis conditions. It has a wide band gap that can only harne…
Probing Photo-excited Charge Carrier Trapping and Defect Formation in Synergistic Doping of SrTiO3
Namitha Anna Koshi, Dharmapura H K Murthy, Sudip Chakraborty +2
Strontium titanate (SrTiO3) is widely used as a promising photocatalyst due to its unique band edge alignment with respect to the oxidation and reduction potential corresponding to…
Influence of Phase Segregation on Recombination Dynamics in Organic Bulk-Heterojunction Solar Cells
Andreas Baumann, Tom J. Savenije, Dharmapura Hanumantharaya K. Murthy +3
We studied the recombination dynamics of charge carriers in organic bulk heterojunction solar cells made of the blend system poly(2,5-bis(3-dodecyl thiophen-2-yl) thieno[2,3-b]thio…
Efficient photogeneration of charge carriers in silicon nanowires with a radial doping gradient
D. H. K. Murthy, T. Xu, W. H. Chen +11
From electrodeless time-resolved microwave conductivity measurements, the efficiency of charge carrier generation, their mobility, and decay kinetics on photo-excitation were studi…
