As a result of their morphology, nanowires bring new properties and the promise of performance for a range of electronic devices. This review looks into the properties of nanowires and the multiple ways in which they have been exploited for energy generation, from photovoltaics to piezoelectric generators.

Nanowire decorated, ultra-thin, single crystalline silicon for photovoltaic devices AURANG, Pantea; Turan, Raşit; Ünalan, Hüsnü Emrah (IOP Publishing, 2017-10-06) Reducing silicon ( Si) wafer thickness in the photovoltaic industry has always been demanded for lowering the overall cost. Further benefits such as short collection lengths and improved open circuit voltages can also be achieved by Si thickness reduction. However, the problem with thin films is poor light absorption. One way to decrease optical losses in photovoltaic devices is to minimize the front side reflection. This approach can be applied to front contacted ultra-thin crystalline Si solar cells to in...
Direct measurement of charge transport through helical poly(ethyl propiolate) nanorods wired into gaps in single walled carbon nanotubes Wang, Nan; Yano, Koji; Durkan, Colm; Plank, Natalie; Welland, Mark E.; Zhang, Yan; Ünalan, Hüsnü Emrah; Mann, Mark; Amaratunga, G. A. J.; Milne, William I. (IOP Publishing, 2009-03-11) We report the direct measurement of electrical transport through rod-like polymer molecules, of poly(ethyl propiolate) (PEP), utilizing single walled carbon nanotubes (SWNTs) as electrodes. The electrical properties of the devices were measured (i) before cutting a SWNT, (ii) when a SWNT was cut and (iii) after PEP deposition into the nanoscale gap in a cut SWNT. The gate-dependent electrical properties showed a reduction in current from I-on = 2.4 x 10(-7) A for SWNT devices to I-on = 3.6 x 10(-9) A for PE...
Silicon nanowire-silver indium selenide heterojunction photodiodes KULAKCI, Mustafa; ÇOLAKOĞLU, Tahir; OZDEMİR, Baris; Parlak, Mehmet; Ünalan, Hüsnü Emrah; Turan, Raşit (IOP Publishing, 2013-09-20) Structural and optoelectronic properties of silicon (Si) nanowire-silver indium selenide (AgInSe2) thin film heterojunctions were investigated. The metal-assisted etching method was employed to fabricate vertically aligned Si nanowire arrays. Stoichiometric AgInSe2 films were then deposited onto the nanowires using co-sputtering and sequential selenization techniques. It was demonstrated that the three-dimensional interface between the Si nanowire arrays and the AgInSe2 thin film significantly improved the ...
Lithium-intercalation oxides for rechargeable batteries Ceder, Gerbrand; VanderVen, Anton; Aydınol, Mehmet Kadri (Springer Science and Business Media LLC, 1998-09-01) Since the introduction of the LixC/LiCoO2 cell, rechargeable lithium batteries have become the technology of choice for applications where volume or weight are a consideration (e.g., laptop computers and cell phones). The focus of current research in cathode-active materials is on less-expensive or higher-performance materials than LiCoO2. This article illustrates how first-principles calculations can play a critical role in obtaining the understanding needed to design improved cathode oxides.
Capacitive cmos readout circuits for high performance mems accelerometers Kepenek, Reha; Külah, Haluk; Department of Electrical and Electronics Engineering (2008) This thesis presents the development of high resolution, wide dynamic range sigma-delta type readout circuits for capacitive MEMS accelerometers. Designed readout circuit employs fully differential closed loop structure with digital output, achieving high oversampling ratio and high resolution. The simulations of the readout circuit together with the accelerometer sensor are performed using the models constructed in Cadence and Matlab Simulink environments. The simulations verified the stability and proper ...
