AC-modulated XPS enables to externally control the electrical field distributions on metal electrode/Ionic Liquid devices
(American Chemical Society, 2024-04-20) Kutbay, Ezgi; İnce, Süleyman; Süzer, Şefik
X-Ray Photoelectron Spectroscopy (XPS) has been utilized to extract local electrical potential profiles by recording core-level binding energy shifts upon application of the AC [square-wave (SQW)] bias with different frequencies. An electrochemical system consisting of a coplanar capacitor with a polyethylene membrane (PEM) coated with the Ionic Liquid (IL) N,N-diethyl-N-methyl-N-(2-methoxyethyl) ammonium bis(trifluoromethanesulfonyl)imide (DEME-TFSI) as the electrolyte is investigated. Analyses are carried out in operando, such that XPS measurements are recorded simultaneously with current measurements. ILs have complex charging/discharging processes, in addition to the formation of Electrical Double Layers (EDL) at the interfaces, and certain properties of these processes can be captured using AC modulation within appropriate time windows of observation. Herein, we select two frequencies, namely, 10 kHz and 0.1 Hz, to separate effects of the fast polarization and slow migratory motions, respectively. Moreover, the local potential developments after adding two equivalent series resistors at three different physical positions of the device have been carefully evaluated from the binding energy shifts in the F 1s peak representing the anion of the IL. This circuit modification allows us to quantify the AC currents passing through the device, as well as the system's impedance, in addition to revealing the potential variations due the IR drops. The complex AC-modulated local XPS data recorded can also be faithfully reproduced using the unmodulated F 1s spectrum and by convoluting it with electrical circuit output provided by the LT-Spice software. The outcome of these efforts is a more realistic equivalent circuit model, which can be related to chemical/physical makeup of the electrochemical system. An important finding of this methodology emerges as the possibility to induce additional local electrical field developments within the device, the directions of which can be reversed controllably.

Analytic thermal modeling for dc to midrange modulation frequency response for thin film high-Tc superconductive edge-transition bolometers
(OSA Publishing, 2001-03-01) Fardmanesh, M.
Thin-film superconductive edge-transition bolometers are modeled with a one-dimensional analytic thermal model with joule heating, film and substrate materials, and the physical interface effects taken into consideration. The results from the model agree well with the experimental results of samples made of large-meander-line Yba(2)Cu(3)O(7-x) films on crystalline SrTiO3, LaAlO3, and MgO substrates up to 100 kHz, the limits of the experimental setup. Compared with the results of the SrTiO3 substrate samples, the results from the model of the LaAlO3 and the MgO substrate samples deviate slightly from the measured values at very low modulation frequencies (below similar to 10 Hz). The deviation increases for higher thermal-conductive substrate materials. When the model was used, the substrate absorption and the thermal parameters of the devices could also be investigated.

Control of the Responsivity and the detectivity of superconductive edge-transition YBa2Cu3O7-x bolometers through substrate properties
(Optical Society of America, 1999-08-01) Fardmanesh, M.; Scoles, K. J.; Rothwarf, A.
The detectivity D* limits of YBa2Cu3O7-x bolometer on 0.05-cm-thick crystalline substrates are investigated, and a method to increase D* to greater than 10(9) (cm Hz(1/2))/W at a 20-mu m wavelength is proposed. Because the response increases proportionally with the bias current I-b, whereas the noise near T-c (the transition or critical temperature) of our MgO and SrTiO3 substrate samples does not, an increase in D* of these samples is obtained by an increase in I-b. Another limiting factor is the de thermal conductance G(0) of the device, which, although controlled by the substrate-holder thermal boundary resistance for our samples, can be changed by means of thinning the substrate to increase D*. The optimal amount of thinning depends on the substrate's thermal parameters and the radiation modulation frequency. D* in our samples is also found to follow the spectral-radiation absorption of the substrate material.

Improved performance of organic light-emitting diodes with MoO3 interlayer by oblique angle deposition
(Optical Society of America, 2011) Liu, S. W.; Divayana, Y.; Sun, X. W.; Wang, Y.; Leck, K. S.; Demir, Hilmi Volkan
We fabricated and demonstrated improved organic light emitting diodes (OLEDs) in a thin film architecture of indium tin oxide (ITO)/molybdenum trioxide (MoO3) (20 nm)/ N,N'-Di(naphth-2-yl)-N,N'-diphenyl-benzidine (NPB) (50 nm)/tris-(8-hydroxyquinoline) (Alq(3)) (70 nm)/Mg:Ag (200 nm) using an oblique angle deposition technique by which MoO3 was deposited at oblique angles (theta) with respect to the surface normal. It was found that, without sacrificing the power efficiency of the device, the device current efficiency and external quantum efficiency were significantly enhanced at an oblique deposition angle of theta = 60 degrees for MoO3.

“Interface: the actual story”
(Inter-Disciplinary Press, 2014) Şenova Tunalı, Funda; Dun, S.; Moser, D.
Technological enhancements and the integration of digital media into our daily lives have brought us many possibilities to form new associations and interact with the content that we are confronted with. Digital storytelling is such a field, which by using the characteristics of new media tries to form new semantic and syntactic relations between the authors/producers/designers/creators, the stories told and the users. Interface appears as the gateway through which the user accesses the content. The physical and digital interfaces (graphical user interfaces) and how the user interacts with them set the rules of the process by which the data is accessed. New media places the interface and the user at the heart of this interaction. The possibility of customising the user experience is an exciting one, which can bring dynamism to any story that is being told. The graphical user interface not only provides access to the content being represented but also gives freedom to the user to a degree on how to experience the story and provides visual information about the look and feel of the story. This chapter probes into the idea that an interface beyond being an undetachable part of the story being told, also acts as a part of the story with which it unfolds. Whether it is an online book, a hyperlinked story, a new media documentary, a computer game, or any other form of transmedia storytelling, interface becomes an important element of the story that gives visual hints and designates the look and feel of the story being told. This study intends to put forward interface as the element that is the gateway to the story, a part of the story and the reflection of the user who access the content through interacting with the interface.
