Assembly of molten transition metal salt surfactant in a confined space for the synthesis of mesoporous metal oxide-rich metal oxide silica thin films
(2011)Uniform and homogeneous coating of mesoporous materials with an active (catalytically, photonic, electrical) nanostructure can be very useful for a number of applications. Understanding chemical reactions in a confined ... -
Atomic force microscopy: Methods and applications
(Elsevier, 2017)This chapter provides an overview of atomic force microscopy, covering the fundamental aspects of the associated instrumentation and methodology as well as representative results from the literature highlighting a variety ... -
Atomic layer deposition: an enabling technology for the growth of functional nanoscale semiconductors
(Institute of Physics Publishing, 2017)In this paper, we present the progress in the growth of nanoscale semiconductors grown via atomic layer deposition (ALD). After the adoption by semiconductor chip industry, ALD became a widespread tool to grow functional ... -
Contact imaging in the atomic force microscope using a higher order flexural mode combined with a new sensor
(A I P Publishing LLC, 1996-01)Using an atomic force microscope (AFM) with a silicon cantilever partially covered with a layer of zinc oxide (ZnO), we have imaged in the constant force mode by employing the ZnO as both a sensor and actuator. The cantilever ... -
Dynamic control of photoresponse in ZnO-based thin-film transistors in the visible spectrum
(IEEE, 2013-04)We present ZnO-channel thin-film transistors with actively tunable photocurrent in the visible spectrum, although ZnO band edge is in the ultraviolet. ZnO channel is deposited by atomic layer deposition technique at a low ... -
Effects of rapid thermal annealing on the structural and local atomic properties of ZnO: Ge nanocomposite thin films
(A I P Publishing LLC, 2015)We have investigated the structural and local atomic properties of Ge nanocrystals (Ge-ncs) embedded ZnO (ZnO: Ge) thin films. The films were deposited by sequential sputtering of ZnO and Ge thin film layers on z-cut quartz ... -
Water-soluble non-polymeric electrospun cyclodextrin nanofiber template for the synthesis of metal oxide tubes by atomic layer deposition
(Royal Society of Chemistry, 2014)We report on the suitability of water-soluble non-polymeric electrospun cyclodextrin (CD) nanofiber templates by using atomic layer deposition (ALD) to yield metal oxide tubes. To demonstrate this, water-soluble electrospun ... -
XPS analysis with external bias: a simple method for probing differential charging
(John Wiley & Sons Ltd., 2004)The XPS spectra of thermally grown oxide layers on Si, Al, W and Hf substrates have been recorded while the samples were subjected to external d.c. voltage bias. The bias induces additional shifts in the measured binding ... -
ZnO based optical modulator in the visible wavelengths
(SPIE, 2013)In order to demonstrate tunable absorption characteristics of ZnO, photodetection properties of ZnO based thin-film transistors are investigated. By controlling the occupancy of the trap states, the optical absorption ...
