182Hf-182W age dating of a 26Al-poor inclusion and implications for the origin of short-lived radioisotopes in the early Solar System.

Proc. Natl. Acad. Sci. U. S. A. 110(22) , 8819-23, (2013)

Refractory inclusions [calcium-aluminum-rich inclusions, (CAIs)] represent the oldest Solar System solids and provide information regarding the formation of the Sun and its protoplanetary disk. CAIs c...

Dispersion engineering of thick high-Q silicon nitride ring-resonators via atomic layer deposition.

Opt. Express 20(25) , 27661-9, (2012)

We demonstrate dispersion engineering of integrated silicon nitride based ring resonators through conformal coating with hafnium dioxide deposited on top of the structures via atomic layer deposition....

Concentration dependence in kinetic arrest of the first-order magnetic transition in Ta doped HfFe2.

J. Phys. Condens. Matter 25(6) , 066011, (2013)

Magnetic behavior of the pseudo-binary alloy Hf(1-x)Ta(x)Fe(2) has been studied, for which the zero-field ferromagnetic (FM) to antiferromagnetic (AFM) transition temperature is tuned near to T = 0 K....
