Carrier Transport01:21

Carrier Transport

The generation of electrical current in semiconductors is fundamentally driven by two mechanisms: drift and diffusion. These processes are essential for the functionality and performance of semiconductor-based devices.
Drift Current:
The drift of charge carriers is started by an external electric field (E). Charged particles, such as electrons and holes, experience an acceleration between collisions with lattice atoms. For electrons, this results in a drift velocity (vd) given by:
Debye–Huckel–Onsager Conductance Equation01:28

Debye–Huckel–Onsager Conductance Equation

The Debye-Hückel-Onsager equation is a cornerstone of physical chemistry, providing a method to determine the molar conductance (Λm) and molar conductance at infinite dilution (Λ°m) for uni-univalent electrolytes.Uni-univalent electrolytes are electrolytes that dissociate in solution to produce one cation with a +1 charge and one anion with a –1 charge per formula unit.This equation addresses two crucial phenomena: the asymmetry effect and the electrophoretic effect. According to this equation,...
Diffusion01:21

Diffusion

Diffusion is a type of passive transport. In passive transport, a substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. For example, take the diffusion of substances through the air. When someone opens a perfume bottle in a room filled with people, the perfume is at its highest concentration in the bottle and is at its lowest at the edges of the room. The perfume vapor will diffuse, or spread away, from the...
Diffusion01:12

Diffusion

Diffusion is the passive movement of substances down their concentration gradients—requiring no expenditure of cellular energy. Substances, such as molecules or ions, diffuse from an area of high concentration to an area of low concentration in the cytosol or across membranes. Eventually, the concentration will even out, with the substance moving randomly but causing no net change in concentration. Such a state is called dynamic equilibrium, which is essential for maintaining overall...

Area of Science:

  • Materials Science
  • Computational Chemistry
  • Electrochemistry

Background:

  • Lithium-ion batteries are crucial for energy storage.
  • Graphene is a promising anode material, but pristine graphene has limitations for lithium diffusion.
  • Defects and doping can modify graphene's properties.

Purpose of the Study:

  • To investigate the impact of nitrogen (N) and boron (B) doping on lithium (Li) diffusion through defected graphene.
  • To determine the energy barriers for Li diffusion in pristine, defected, and doped graphene.
  • To evaluate the potential of these modified graphene structures as anode materials for Li-ion batteries.

Main Methods:

  • First-principles calculations based on density functional theory (DFT).
  • Simulation of Li diffusion pathways through various graphene structures (pristine, monovacancy, divacancy).
  • Analysis of doping effects (N and B) on Li diffusion energy barriers and binding energies.

Main Results:

  • Lithium diffusion through pristine graphene is hindered by a high energy barrier.
  • Divacancy defects significantly reduce the Li diffusion barrier (1.34 eV).
  • N-doping in monovacancy graphene lowers the barrier, with increasing N atoms reducing it further.
  • N-doping in divacancy graphene enhances Li binding energy.
  • B-doping in monovacancy graphene increases the barrier.
  • B-doping in divacancy graphene reduces the barrier to 1.54 eV, suggesting good kinetics.

Conclusions:

  • Defected graphene, particularly with divacancies, offers lower energy barriers for Li diffusion compared to pristine graphene.
  • Nitrogen and boron doping, especially in conjunction with divacancy defects, can further optimize Li diffusion kinetics.
  • Divacancy, B-doped, and N-doped defected graphene are promising alternatives to pristine graphene for Li-ion battery anode applications.
