This paper presents the results of studying characteristics hydrogen sensors based on thin In2O3 films modified with tin and dysprosium dispersed double Pt/Pd catalysts deposited surface. To control content Sn Dy in films, an original technology was developed, ceramic targets were fabricated from powders In–Dy–O, Dy–Sn–O, In–Dy–Sn–O systems synthesized by sol–gel method. Films complex compositi...

A comparison of methods to create Ohmic contacts to semiconductor nanowires NWs and carbon nanotubes CNTs is presented. A Ni/Au lift-off metallization was used to contact GaN and In2O3 NWs and CNTs using electron-beam e-beam or optical lithography. In order to render the metal-semiconductor contacts Ohmic, e-beam-processed devices are found to require a postfabrication, high-temperature anneal,...

We have synthesized three-dimensional self-assembled ZnO-based nanoscale heterostructures through the addition of alloying elements (In or Sn) during the vapor phase transport and condensation deposition process. Each threedimensional nanoscale heterostructure consists of a faceted nanowire core, with side branches (nanoribbons or nanorods) emanating from facets of the central nanowire core. Th...

A combinatorial high-throughput temperature-programmed method to obtain the optimal operating temperature (OOT) of gas sensor materials is demonstrated here for the first time. A material library consisting of SnO2, ZnO, WO3, and In2O3 sensor films was fabricated by screen printing. Temperature-dependent conductivity curves were obtained by scanning this gas sensor library from 300 to 700 K in ...

Reducing indium consumption, which is related to the transparent conductive oxide (TCO) use, a key challenge for scaling up silicon heterojunction (SHJ) solar cell technology terawatt level. In this work, we developed bifacial SHJ cells with reduced TCO thickness. We present three types of In2O3-based TCOs, tin-, fluorine-, and tungsten-doped In2O3 (ITO, IFO, IWO), whose thickness has been opti...

Thin film transistors (TFTs) are key components for the fabrication of electronic and optoelectronic devices, resulting in a push wider exploration semiconducting materials cost-effective synthesis processes. In this report, simple approach is proposed to achieve 2-nm-thick indium oxide nanosheets from liquid metal surfaces by employing squeeze printing technique thermal annealing at 250 °C air...
