¹³C NMR: ¹H–¹³C Decoupling01:04

¹³C NMR: ¹H–¹³C Decoupling

The probability of having two carbon-13 atoms next to each other is negligible because of the low natural abundance of carbon-13. Consequently, peak splitting due to carbon-carbon spin-spin coupling is not observed in spectra. However, protons up to three sigma bonds away split the carbon signal according to the n+1 rule, resulting in complicated spectra.
A broadband decoupling technique is used to simplify these complex, sometimes overlapping, signals. Broadband decoupling relies on a...
Standing Waves in a Cavity01:28

Standing Waves in a Cavity

A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:
Double Resonance Techniques: Overview01:12

Double Resonance Techniques: Overview

Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.
Spin decoupling is usually achieved by...

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Nanotechnology

Background:

  • Two-dimensional (2D) materials, including graphene and graphene-related materials (GRMs), are vital for next-generation electronics.
  • Substrate interactions induce strain in GRMs, altering their electronic properties and enabling the field of straintronics.
  • Developing rapid, non-invasive methods to probe strain in large areas of 2D materials is essential for device research.

Purpose of the Study:

  • To demonstrate an all-optical imaging technique for mapping strain distribution in 2D material monolayers.
  • To investigate strain induced in a WS2 monolayer on a patterned Si/SiO2 substrate using Polarization-resolved Second Harmonic Generation (P-SHG).
  • To correlate optical measurements with atomic force microscopy and Raman spectroscopy for strain confirmation.

Main Methods:

  • Utilized Polarization-resolved Second Harmonic Generation (P-SHG) optical imaging to detect strain.
  • Applied pixel-by-pixel fitting of P-SHG data to generate spatially resolved images of the crystal armchair direction.
  • Employed atomic force microscopy (AFM) and Raman mapping for independent verification of strain.

Main Results:

  • Successfully identified strain distribution in a single-layer WS2 on a pre-patterned substrate.
  • Observed a distinct cross-shaped pattern in armchair direction images in strained regions where WS2 conformed to the substrate topography.
  • Confirmed the presence of strain through complementary AFM and Raman spectroscopy analyses.

Conclusions:

  • P-SHG imaging serves as an effective, minimally invasive tool for mapping strain in 2D materials over large areas.
  • The findings highlight the potential of P-SHG for quality control and development in 2D electronic devices.
  • Strain engineering in 2D materials can be precisely characterized using this advanced optical imaging technique.
