$Interference and Diffraction$ 02:18

Interference and Diffraction

Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

Two-Dimensional (2D) NMR: Overview

Two-Dimensional (2D) NMR: Overview

The 1D NMR spectrum of large and complex molecules like natural products has complicated splitting patterns and overlapping signals, which can be easily interpreted using 2-dimensional (2D) NMR. Unlike 1D NMR, 2D NMR has two frequency axes that provide the coupling information between the nucleus A and nucleus B in a molecule. The process from which 2D spectra are obtained has four steps.
The first step is the preparation period, during which nucleus A is excited with a radiofrequency pulse....

Energy Bands in Solids

Energy Bands in Solids

Isolated atoms have discrete energy levels that are well described by the Bohr model. And, it quantifies the energy of an electron in a hydrogen atom as En. Higher quantum numbers 'n' yield less negative, closer electron energy levels.
Band Formation:
When atoms are brought close together, as in a solid, these discrete energy levels begin to split due to the overlap of electron orbitals from adjacent atoms. This split occurs because of the Pauli exclusion principle, which states...

Fluid Mosaic Model

Fluid Mosaic Model

Scientists identified the plasma membrane in the 1890s and its principal chemical components (lipids and proteins) by 1915. The model for plasma membrane structure, proposed in 1935 by Hugh Davson and James Danielli, was the first model to be widely accepted in the scientific community. The model was based on the plasma membrane's "railroad track" appearance in early electron micrographs. Davson and Danielli theorized that the plasma membrane's structure resembled a sandwich...

The Fluid Mosaic Model

The Fluid Mosaic Model

The fluid mosaic model was first proposed as a visual representation of research observations. The model comprises the composition and dynamics of membranes and serves as a foundation for future membrane-related studies. The model depicts the structure of the plasma membrane with a variety of components, which include phospholipids, proteins, and carbohydrates. These integral molecules are loosely bound, defining the cell’s border and providing fluidity for optimal function.

Bewley Lattice Diagram

Bewley Lattice Diagram

The Bewley lattice diagram, developed by L. V. Bewley, effectively organizes the reflections occurring during transmission-line transients. It visually represents how voltage waves propagate and reflect within a transmission line, making it easier to understand the complex interactions that occur.

Background:

Moiré engineering in twisted bilayer graphene enables correlated electronic states.
Flat bands in such systems typically require small twist angles and are fragile due to weak van der Waals coupling.

Purpose of the Study:

To explore an alternative mechanism for flat-band formation.
To investigate the potential of twisted graphite and related structures for robust flat bands.

Main Methods:

Investigated interlayer sp3 hybridization in twisted graphite.
Identified three-dimensional diamond-like carbon phases with moiré features (moiré diamonds).
Analyzed the electronic band structure of these moiré diamonds.

Main Results:

Demonstrated flat-band formation via interlayer sp3 hybridization, stabilizing large-angle moiré superstructures through covalent bonding.
Observed two-dimensional flat bands in moiré diamonds, nearly dispersionless in-plane but dispersive along k_z.
These flat bands emerge at large twist angles with short moiré periods and exhibit robustness.

Conclusions:

Covalently bonded moiré diamonds offer a new platform for flat-band physics.
This approach overcomes limitations of van der Waals coupling in traditional moiré systems.
Provides a pathway for robust flat-band engineering in novel carbon phases.
