Self-Concept

1.7K
Self-concept is the cognitive and emotional understanding individuals hold about their identity. It evolves through various developmental stages, beginning in infancy and maturing as children grow. This concept influences how individuals perceive their abilities, interact with others, and manage challenges throughout life.
Infancy and Emerging Recognition
During infancy, self-concept is virtually nonexistent. Babies do not distinguish themselves as separate entities and often mistake their...

Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process...

The center-of-mass framework helps to easily describe the work done on rigid bodies. Since the internal forces in a rigid body do no work, they can be ignored, and the external forces can be considered in the work-energy theorem.
The work done by gravity to move a rigid body, or the work done by an opposing force to move a rigid body against gravity, can be calculated using the center-of-mass framework. It is the line integral of the force of gravity over the path, considered positive if...

The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Nanotechnology

Background:

  • Janus transition metal dichalcogenides (TMDs) are emerging 2D materials with inherent cross-plane (cp) asymmetry and large cp dipoles.
  • These materials offer unique electronic and optical properties due to their broken inversion symmetry.

Purpose of the Study:

  • To investigate the electronic properties of stacked graphene and Janus MoSSe structures.
  • To demonstrate the formation of atomically thin pn-junctions and analyze charge transport mechanisms.
  • To evaluate the potential of these heterostructures in optoelectronic applications, particularly photovoltaics.

Main Methods:

  • First-principles calculations were employed to model the electronic structure and properties.
  • A tailored charge transport method was utilized to simulate device performance.
  • Heterostructures of graphene and Janus MoSSe were computationally designed and analyzed.

Main Results:

  • Record high homogeneous doping of graphene was achieved when stacked with Janus MoSSe.
  • Abrupt, atomically thin, cross-plane pn-junctions were successfully formed.
  • Graphene demonstrated its capability to act as an electrode without screening the cp dipole.
  • A large photocurrent response was predicted, dominated by a cp transport channel.

Conclusions:

  • Graphene-Janus MoSSe heterostructures exhibit significant potential for electronic and optoelectronic devices.
  • The observed high photocurrent, exceeding that of silicon, highlights their promise for advanced photovoltaic applications.
  • The unique properties of Janus TMDs, combined with graphene, pave the way for novel device architectures.
