Surface engineered angstrom thick ZnO-sheathed TiO2 nanowires as photoanodes for performance enhanced dye-sensitized solar cells
(Royal Society of Chemistry, 2014)
This paper presents a systematic study on the effects of angstrom-thick atomic layer deposited (ALD) ZnO sheaths on hydrothermally-grown TiO2 nanowires (NWs) used as photoanodes in dye-sensitized solar cells (DSSCs). We ...
Enhanced photoresponse of conformal TiO2/Ag nanorod array-based Schottky photodiodes fabricated via successive glancing angle and atomic layer deposition
(AVS Science and Technology Society, 2015)
In this study, the authors demonstrate a proof of concept nanostructured photodiode fabrication method via successive glancing angle deposition (GLAD) and atomic layer deposition (ALD). The fabricated metal-semiconductor ...
Electronic and optical device applications of hollow cathode plasma assisted atomic layer deposition based GaN thin films
(A I P Publishing LLC, 2015)
Electronic and optoelectronic devices, namely, thin film transistors (TFTs) and metal-semiconductor-metal (MSM) photodetectors, based on GaN films grown by hollow cathode plasma-assisted atomic layer deposition (PA-ALD) ...
Resistive Switching based electro-optical modulation
(Wiley, 2014-09-08)
Resistive switching enables optical modulation via atomic scale modifications that induce change in the refractive index of active device materials. The formation of filaments and migration of atoms around these filaments ...
Performance enhancement of GaN metal-semiconductor-metal ultraviolet photodetectors by insertion of ultrathin interfacial HfO2 layer
(AVS Science and Technology Society, 2015)
The authors demonstrate improved device performance of GaN metal-semiconductor-metal ultraviolet (UV) photodetectors (PDs) by ultrathin HfO2 (UT-HfO2) layer on GaN. The UT-HfO2 interfacial layer is grown by atomic layer ...
