Overview

Takashi Sekiguchi is affiliated with the University of Tsukuba in Japan and has contributed extensively to fields spanning Engineering and Materials Science. Their research work encompasses several subfields, prominently Electrical and Electronic Engineering, Materials Chemistry, Mechanics of Materials, Atomic and Molecular Physics and Optics, and Condensed Matter Physics.

The main topics addressed in Sekiguchi's publications include Semiconductor materials and devices, Metal and Thin Film Mechanics, GaN-based semiconductor devices and materials, Electron and X-Ray Spectroscopy Techniques, Grouting, Rheology, and Soil Mechanics, Perovskite Materials and Applications, and Surface and Thin Film Phenomena.

Frequent publication venues reflect these topics and include Microscopy, Journal of Applied Physics, Journal of Electronic Materials, SSRN Electronic Journal, and Journal of Surface Analysis.

Several recent papers showcase the scope of Sekiguchi's research:

  • Improving the Open-Circuit Voltage of Sn-Based Perovskite Solar Cells by Band Alignment at the Electron Transport Layer/Perovskite Layer Interface (2020, ACS Applied Materials & Interfaces)
  • Stable single atomic silver wires assembling into a circuitry-connectable nanoarray (2021, Nature Communications)
  • Influence of implanted Mg concentration on defects and Mg distribution in GaN (2020, Journal of Applied Physics)
  • Mg diffusion and activation along threading dislocations in GaN (2020, Applied Physics Letters)
  • Composition dependent properties of p- and n-type polycrystalline group-IV alloy thin films (2021, Journal of Alloys and Compounds)

Sekiguchi has collaborated frequently with fellow researchers such as Jun Chen, Tadakatsu Ohkubo, Wei Yi, Ryo Tanaka, and Shinya Takashima. The number of coauthored works ranges predominantly from six to twelve for these frequent collaborators.

The combined focus on semiconductor materials, thin film mechanics, and spectroscopy techniques indicates an integrative approach bridging applied physics and materials chemistry. The prominence of GaN-based materials and perovskite applications aligns their profile with contemporary topics in electronic materials research.
