Characterization of amorphous silicon and silicon nanoparticle films using variable angle spectroscopic ellipsometry
Contributor:Valentine, Clare; Klafehn, Grant; Airuoyo, Idemudia; Kendrick, Chito; Furtak, Thomas; Collins, Reuben
Raman characterization of ZnO and Si nanowires
Contributor:Whalen, Jessica; Collins, Reuben; Furtak, Thomas
Organic Photovoltaics (OPVs) have gained favor recently for low production cost and potential for roll-to-roll flexible substrates. Though efficiency is fundamentally less than commercial PVs, low production temperature ...
Successive ionic layer adsorption and reaction for organic/inorganic interfaces
Contributor:Hunt, Heather; Collins, Reuben; Furtak, Thomas
Zinc oxide is a promising material for use in organic electronics, particularly organic photovoltaics (OPVs). ZnO has a large band gap around 3.3 eV, has a high electron mobility, is non-toxic, and can be processed using ...
Raman spectroscopy of silicon quantum dots
Contributor:Rachel, Kurchin; Kendrick, Chito; Collins, Reuben; Furtak, Thomas
Silicon quantum dots are synthesized and studied extensively by REMRSEC, but they have not thus far had a fast and reliable way to characterize them. In this work, Raman spectroscopy is employed to study dots in varying ...
Etch Resistant Zn1-xMgxO alloys as an e'-acceptor for dye sensitized solar cells
Contributor:Meing, Erich; Brenner, Thomas; Collins, Reuben; Furtak, Thomas
In DSSCs, dyes are used to photosensitize a nanoporous electrode, most commonly TiO2. Light excites the dye, which then transfers an electron to the metal oxide electrode. The electron then travels to the conducting contact ...
Using AFM to find evidence of conformal monolayers
Contributor:Meinig, Erich; Brenner, Thomas; Chen, Gang; Collins, Reuben; Furtak, Thomas
Atomic force microscopy (AFM) is one of the tools used to infer whether a conformal monolayer of the surface treatment exists. AFM roughness measurements can be used to detect changes in height before and after surface ...
Catalyst-free 'click chemistry' of zinc oxide surfaces
Contributor:Evans, Charlotte; Brenner, Thomas; Chen, Gang; Collins, Reuben; Furtak, Thomas
Click chemistry' describes reactions that can modify the surface functionality of a material simply and quickly by joining small molecules together. In this research, a five step process was developed involving the surface ...
Benzoic acid surface functionalization of conduction band engineered Zn1-xMgxO layers for enhanced organic/inorganic photovoltaics
Contributor:Flores, Tom; Brenner, Thomas; Chen, Gang; Furtak, Thomas; Collins, Reuben
Increasing the efficiency of organic/inorganic photovoltaics will open the door to a cheap, easy, and safe means to bring solar energy to the masses. A key role in raising this efficiency is by maximizing the band gap ...
