Atomic Layer Deposition of Vanadium Dioxide and a Temperature-dependent Optical Model

12.4K
Thin films (100-1000 Å) of vanadium dioxide (VO2) were created by atomic-layer deposition (ALD) on sapphire substrates. Following this, the optical properties were characterized through the metal-insulator transition of VO2. From the measured optical properties, a model was created to describe the tunable refractive index of...

Human Fear Conditioning Conducted in Full Immersion 3-Dimensional Virtual Reality

21.4K
Classical fear conditioning paradigm was adapted for human participants in a fully immersive virtual reality setting. Using a discrimination paradigm, conditioned fear, cue and context memory retention, and extinction was measured with skin conductance response to dynamic virtual snakes and spiders (the conditioned stimuli) in two distinct virtual contexts.

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Optoelectronics

Background:

  • Complex optical conductivities of 2D materials are crucial for optoelectronic devices.
  • Understanding layer-dependent optical properties is key to material application.

Purpose of the Study:

  • To systematically investigate the layer-dependent optical conductivity of 1-6 layer 2D MoS2.
  • To analyze spectral features and their evolution with increasing layer number.
  • To understand the underlying physical mechanisms driving these changes.

Main Methods:

  • Spectroscopic ellipsometry was employed to measure optical conductivity.
  • Measurements covered an ultrawide spectral range (0.73-6.42 eV).
  • Analysis focused on identifying and characterizing spectral peaks (A-E).

Main Results:

  • Five distinct feature peaks (A-E) were identified in the optical conductivity spectra.
  • Peaks A and B showed minimal dependence on layer number.
  • Peaks C and D exhibited redshifts with increasing layer number, indicating band shrinkage and changing exciton effects.

Conclusions:

  • Layer-dependent optical conductivity in 2D MoS2 is governed by a interplay between exciton effects and band shrinkage.
  • The study provides experimental insights into the optical properties of few-layer MoS2.
  • The applicability of theoretical models for evaluating optical conductivity in 2D materials was discussed.
