    Synthesis and characterization of Cu-Chalcogenide nanocrystals for potential applications in low-cost solar cells by Ahmadi, Mahshid

    Published 2013
    “…Since the opto-electrical properties of the NCs are highly dependent on the composition and crystal structure, X-ray diffraction, selected area electron diffraction, convergent beam electron diffraction and Raman spectroscopy were used to determine their crystal structure. …”

    Topochemical fluorination of some Ruddlesden-Popper phases by Zhang, R

    Published 2017
    “…The introduction of a cooperative octahedral tilt around the crystallographic z-axis leads to a local breaking of the inversion symmetry of the host lattice on fluorination, although the global inversion symmetry of the lattice is retained due to an alternation in the z-tilt direction in adjacent perovskite sheets.</p> <p>The substitution of Sr<sup>2+</sup> with Ca<sup>2+</sup> cations in YSr<sub>2</sub>Mn<sub>2</sub>O<sub>7</sub> led to an increasing distortion of the metal-oxide framework, resulting in the formation of an orthorhombic symmetry in space group <em>Pnnm</em> adopted by YSr<sub>0.5</sub>Ca<sub>1.5</sub>Mn<sub>2</sub>O<sub>7</sub>. …”

    Design and analysis of passive phase shifters using controllable defected ground structures in 65nm CMOS technology for 77-81 GHz automotive radar by Wu, Jiaqi

    Published 2024
    “…Phased array radar is a low cost and promising technique to achieve high angular resolution by scanning a narrow beam in azimuth. The key enabler of a phased array radar is the phase shifter, which provides a progressive phase difference in each channel to achieve beamforming. …”

    Solution processed transition metal oxides selective contacts for Si heterojunction solar cells by Lu, Chenjin

    Published 2021
    “…In this work, we have first prepared hole selective contacts using solution processed MoOx (s-MoOx) by spin-coating and physical evaporated MoOx (e-MoOx) by electron beam evaporator. The performance of the s-MoOx/Si HSC has been investigated and optimized, which has been demonstrated solar cell efficiency of 12.5% for s-MoOx/Si HSC that is comparable to efficiency of 13.3% for e-MoOx/Si HSC. …”

    Development of highly efficient organic and perovskite solar cells by Li, Xianqiang

    Published 2018
    “…The top Au electrodes are normally deposited by vacuum deposition methods, such as thermal evaporator and E-beam evaporator. The vacuum deposition methods increase the fabrication costs of organic solar cells and perovskite solar cells and are not compatible with roll-to-roll manufacturing process. …”
