Microwave synthesis of superparamagnetic cobalt-ferrite thin films for RF CMOS applications
In the era of 5G technologies, the emphasis is on getting all the devices, active or passive to work in high frequencies. Higher efficiency chips can be obtained by combining both the active and passive devices on a single ...
Continuous-Wave Supercontinuum Generation using Cascaded Raman Fiber Lasers
This thesis explains architecture and techniques to generate high power, CW
supercontinuum laser sources using standard Silica fibers as the nonlinear medium, pumped
using high power CW Yb doped fiber lasers. Unlike the ...
Transition metal oxide absorbers for photovoltaics
Several oxides are non-toxic, stable, and can be deposited using inexpensive techniques on a variety of substrates. There is a compelling case for use of oxide in photovoltaics, referred to as “all-oxide photovoltaics”. ...
