The de Broglie Wavelength02:32

The de Broglie Wavelength

35.1K
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Energy Bands in Solids01:01

Energy Bands in Solids

2.6K
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...

Band Theory02:35

Band Theory

18.0K
When two or more atoms come together to form a molecule, their atomic orbitals combine and molecular orbitals of distinct energies result. In a solid, there are a large number of atoms, and therefore a large number of atomic orbitals that may be combined into molecular orbitals. These groups of molecular orbitals are so closely placed together to form continuous regions of energies, known as the bands.
The energy difference between these bands is known as the band gap.

Bewley Lattice Diagram01:12

Bewley Lattice Diagram

1.6K
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.

Two-Dimensional (2D) NMR: Overview01:12

Two-Dimensional (2D) NMR: Overview

1.8K
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....

Metallic Solids02:37

Metallic Solids

21.6K
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...

Background:

  • Graphene discovery spurred interest in novel two-dimensional (2D) materials.
  • Research focus shifted from synthesis to modification of 2D materials, particularly electronic structures.

Purpose of the Study:

  • To review methods for altering the band structures of 2D materials.
  • To discuss the impact of these modifications on electronic and physical properties.

Main Methods:

  • Alloying 2D materials to form ternary compounds (e.g., h-BCN, ternary TMDs).
  • Vertically stacking 2D materials to create van der Waals (vdW) solids and lateral heterostructures.
  • Controlling the thickness (number of layers) of 2D materials.

Main Results:

  • Ternary 2D materials offer tunable electronic structures.
  • 2D heterostructures (vertical and lateral) enable novel electronic properties.
  • Thickness control significantly impacts band structure and properties in materials like TMDs and black phosphorus (BP).
