Journal ArticleDOI

Lead-Free Highly Efficient Blue-Emitting Cs3Cu2I5 with 0D Electronic Structure

TL;DR: New halide materials that meet the requirements of: (i) nontoxicity, (ii) high PLQY, and (iii) ease of fabrication of thin films via the solution process are explored.
Journal ArticleDOI

Amorphous IGZO TFT with High Mobility of ∼70 cm2/(V s) via Vertical Dimension Control Using PEALD

TL;DR: In-rich IGZO TFTs consisting of vertically stacked InOx and GaZnOx atomic layers fabricated at a low deposition temperature (200 oC) exhibit significantly high mobilities of ~80 cm2/Vs while keeping a reasonable carrier density of ~1017 cm-3.
Journal ArticleDOI

Transparent amorphous oxide semiconductors for organic electronics: Application to inverted OLEDs

TL;DR: This approach provides a solution to the problem of fabricating oxide thin-film transistor-driven OLEDs with both large size and high stability.
Journal ArticleDOI

Conversion of an ultra-wide bandgap amorphous oxide insulator to a semiconductor

TL;DR: Kim et al. as discussed by the authors showed that high partial pressures of oxygen gas during rapid laser deposition transforms amorphous gallium oxide films into semiconductors, achieving an electron Hall mobility of 8.5 cm2V−1.
Journal ArticleDOI

Exploration of Stable Strontium Phosphide-Based Electrides: Theoretical Structure Prediction and Experimental Validation

TL;DR: Although density functional calculations with the generalized gradient approximation predict Sr5P3 to be a metal, electrical conductivity measurement reveal semiconducting properties characterized by a distinct band gap, which indicates that the newly synthesized Sr 5P3 is an ideal one-dimensional electride with the half-filled band by unpaired electrons.
