    Abstract:

    Governments around the world adopt transparency reforms to facilitate accountability. In principle, open proceedings provide citizens with valuable information to evaluate elected officials’ decisionmaking, which incentives lawmakers to follow mass preferences when choosing policies. However, the public’s general lack of knowledge and engagement with the political process may weaken the power of open information, and perhaps instead allow citizens and groups with extreme views to exer…

    Abstract:

    Spreading resistance microscopy (SRM) was used to study nanoscale variations in electronic and structural properties of an ultrathin near-surface GaN/AlN quantum well (QW). In the SRM images of the growth surface of the GaN/AlN QW heterostructure, an inhomogeneous current contrast was detected in the form of disk-like regions of increased conductivity with the sizes in the range of 50–160 nm and a density of 1.7 109 cm 2 . Analysis of the current contrast dependence on the polarity of the sam…

    Abstract:

    The 1T phase of tantalum disulfide (1T-TaS 2 ) possesses a variety of charge-density-wave (CDW) orders, and as a result, it attracts an increasing amount of academic and technological interest. The 1T phase of tantalum disulfide (1T-TaS 2 ) possesses a variety of charge-density-wave (CDW) orders, and as a result, it attracts an increasing amount of academic and technological interest. Researchers have devoted tremendous efforts towards understanding the impacts of doping, alloying, intercalat…

    Abstract:

    High-throughput combinatorial investigations are transforming materials discovery, phase diagram development, and processing optimization. Thin-film deposition techniques are frequently used to fabricate sample libraries employed in these studies. Various adaptations of well-known thin-film chemical vapor deposition (CVD) and physical vapor deposition (PVD) techniques utilized for the synthesis of inorganic combinatorial thin-film materials libraries are reviewed, with novel processing approa…

    Abstract:

    GaAs-based microdisk lasers with an active region representing a dense array of indium-rich islands (InGaAs quantum well-dots) were studied using direct small-signal modulation. We demonstrate that using dense arrays of InGaAs quantum well-dots enables uncooled high-frequency applications with a GHz-range bandwidth for microdisk lasers. A maximum 3 dB modulation frequency of 5.9 GHz was found in the microdisk with a radius of 13.5 μm operating without a heatsink for cooling. A modulation curr…
