The Effect of Anodization Parameters on the Aluminum Oxide Dielectric Layer of Thin-Film Transistors12:32

The Effect of Anodization Parameters on the Aluminum Oxide Dielectric Layer of Thin-Film Transistors

9.2K
Anodization parameters for growth of the aluminum-oxide dielectric layer of zinc-oxide thin-film transistors (TFTs) are varied to determine the effects on the electrical parameter responses. Analysis of variance (ANOVA) is applied to a Plackett-Burman design of experiments (DOE) to determine the manufacturing conditions that result in optimized device...

Thin layer chromatography (TLC) is a chromatographic method used to separate mixtures of non-volatile compounds. A TLC plate consists of a thin layer of adsorbent material (the stationary phase) fixed to an appropriate solid support such as plastic, aluminum, or glass1. The sample(s) and reference compound(s) are dissolved in an appropriate solvent and applied near the bottom edge of the TLC plate in...

Metallic Solids

20.5K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Source: Okamoto, A., et al. Self-standing Electrochemical Set-up to Enrich Anode-respiring Bacteria On-site. J. Vis. Exp. (2018)This video demonstrates the use of an on-site electrochemical system to enrich anode-respiring bacteria (ARB) from natural reservoirs. A redox gradient is established by placing the anode in oxygen-free deep water and the cathode in oxygen-rich surface water. ARB form biofilms and transfer electrons to the anode, which flows to the cathode, where oxygen is reduced,...

Area of Science:

  • Materials Science
  • Electrochemistry
  • Energy Storage

Background:

  • Lithium-metal batteries are promising for next-generation energy storage due to the high capacity and low potential of lithium anodes.
  • However, practical application is limited by lithium dendrite formation and interface reactions.

Purpose of the Study:

  • To develop a protective layer for lithium anodes to enhance stability and performance in lithium-sulfur batteries.
  • To investigate the efficacy of a silver nitrate-modified lithium anode (AMLA) in suppressing dendrites and corrosion.

Main Methods:

  • Constructing a difunctional protecting layer using silver nitrate on the lithium anode surface.
  • Investigating the layer's ability to prevent corrosion from intermediate polysulfides (Li2Sx, 4 ≤ x ≤ 8).
  • Analyzing dendrite suppression through regulation of lithium nucleation and deposition.

Main Results:

  • The AMLA demonstrated stable cycling for over 50 hours at 5 mA cm⁻² with an overpotential below 0.2 V.
  • The protected anode maintained a high capacity of 666.7 mAh g⁻¹ after 500 cycles at 0.8375 mA cm⁻² in a Li-S cell.
  • The protective layer effectively regulated lithium deposition and suppressed dendrite growth.

Conclusions:

  • The silver nitrate-modified lithium anode (AMLA) provides effective protection against dendrites and polysulfide corrosion.
  • This protective strategy significantly enhances the stability and cycle life of lithium-sulfur batteries.
  • The AMLA shows great potential for advancing the practical application of lithium-metal batteries.
