Rad, Adeleh Granmayeh (author), Abbasi, H. (author)Silver oxide (AgO) thin films were prepared by using a cylindrical direct current reactive magnetron sputtering system at 10<sup>−5</sup> torr initial pressure on BK7 glass substrate. Samples deposited for 3, 5 and 7 minutes. Surface characterization of AgO thin films in the nanometer scale can be accurately determined using the atomic force...journal article 2023

Sun, J. (author)Atmospheric aerosols are solid or liquid particles suspended in the air. The majority of them are produced by natural processes, including sea salt from oceans, mineral dust from (semi-)arid regions, carbon containing particles from wildfires, and sulfates and ash from volcanic activities. Anthropogenic aerosols are produced by industrial...doctoral thesis 2022

(author), Castellanos-Gomez, Andres (author)An interesting aspect of 2D materials is the change of their electronic structure with the reduction of thickness. Molybdenum and tungsten-based transition metal dichalcogenides form an important family of 2D materials, whose members show a thickness-dependent bandgap and strong light–matter interaction. In this work, the experimental...journal article 2019

(author)A key enabling step in leveraging the properties of nanoparticles (NPs) is to explore new, simple, controllable, and scalable nanotechnologies for their syntheses. Among "wet" methods, cathodic corrosion has been used to synthesize catalytic aggregates with some control over their size and preferential faceting. Here, we report on a...journal article 2018

Mehrali, M. (author), Ghatkesar, M.K. (author), Pecnik, Rene (author)The wide-spread adoption of solar thermal absorbers is currently hampered by their low absorption efficiencies and their high capital cost. As a result, a number of initiatives, including direct absorption solar collectors (DASC), are currently underway to improve the absorber efficiencies. In this regard, this study focused on application of...journal article 2018

Rezaei, N. (author), Isabella, O. (author), Vroon, Zeger (author), Zeman, M. (author)A 3-D optical modelling was calibrated to calculate the light absorption and the total reflection of fabricated CIGS solar cells. Absorption losses at molybdenum (Mo) / CIGS interface were explained in terms of plasmonic waves. To quench these losses, we assumed the insertion of a lossless dielectric spacer between Mo and CIGS, whose optical...journal article 2018

Liu, Y. (author), Salemink, H.W.M. (author)A planarized on-chip nanophotonic sensor based on a photonic crystal cavity is realized in this work. The sensor was embedded in a solid protecting material (flowable oxide) with perfect filled holes: this eliminates problems of fouling in practical applications. The functional area of the sensor is created by carefully removing the...journal article 2017

(author), Zwiller, Val (author)In this paper, we characterize the Thermo-optic properties of silicon nitride ring resonators between 18 and 300 K. The Thermo-optic coefficients of the silicon nitride core and the oxide cladding are measured by studying the temperature dependence of the resonance wavelengths. The resonant modes show low temperature dependence at cryogenic...journal article 2016

Ramanandan, G.K.P. (author), Adam, A.J.L. (author), Ramakrishnan, G. (author), Petrik, P. (author), Hendrikx, R. (author), Planken, P.C.M. (author)We show that the interface between gold and thermally formed cuprous oxide, which emits terahertz radiation when illuminated with ultrafast femtosecond lasers, is in fact an AuCu/Cu2O interface due to the formation of the thermal diffusion alloy AuCu. The alloy enables the formation of a Schottky-barrier-like electric field near the interface...journal article 2014

Ramakrishnan, G. (author), Chakkittakandy, R. (author), Planken, P.C.M. (author)Generation of subpicosecond terahertz pulses is observed when graphite surfaces are illuminated with femtosecond near-infrared laser pulses. The nonlinear optical generation of THz pulses from graphite is unexpected since, in principle, the material possesses a centre of inversion symmetry. Experiments with highly oriented pyrolytic graphite...journal article 2009

Delil, A.A.M. (author)Radiation heat transfer is a non-negligible physical process in an open-cycle magnetohydrodymic generator. It constitutes an important part of the energy conservation law, one of the fundamental equations describing the behaviour of the MHD combustion gas in the generator. Radiation heat transfer is modelled following the generally accepted...report 1983
