Before understanding the shape of electrons and their behavior, first, let’s see what electrons are

What is electronics?

Electrons are tiny particles with negative charges. It can move freely or remain connected to atoms. Inside the atom, it works with protons and neutrons, which are other major building blocks. Unlike protons and neutrons that remain in the center of an atom (called a nucleus), electrons move around it in a specific path. The negative charge of electrons balances the positive charge of protons, keeping the atomic stable when the quantity matches. Electrons are very different from protons and neutrons. They are lighter and act like waves and particles, rather than made from smaller parts. On the other hand, protons and neutrons are composed of tiny particles called quarks.

What is the shape of an electron?

The dual properties of electrons:

Electrons are not only small particles moving in a straight line. They exhibit wave-particle duality, meaning they are both particles and waves. This property makes tracking and predicting its movement challenging. Scientists compared the motion of electrons to ripples in ponds—sometimes forming smooth waves, while other times twisted into complex, unpredictable patterns.

Atomic orbital shape

The electrons in an atom use different waveforms according to the energy level:

  • S-orbit: spherical.
  • p-track: dumbbell shape.
  • D-Trail: Four-leaf clover three-leaf clover pattern.
  • Higher track: More complex geometric patterns.

Electronic shapes in different situations

  • Free electrons: spherical symmetric electric field distribution.
  • Binded electrons (in atoms): complex waveform structure.
  • Quantum wells (such as lasers): electrons behave like traditional waves.

Understand electronic behavior

Key Discovery

  • Electrons do not behave like traditional solid particles; they exhibit wavy properties.
  • Scientists use angle-resolved light emission spectroscopy (ARPE) to map electron geometry.
  • The discovery could advance quantum computing, superconductors and matter science.

How scientists map the shape of electrons

Electrons exhibit dual properties because they manifest themselves in particles and waves. Due to their ability to move in unpredictable patterns, drawing their shapes is challenging. Scientists used ARPE, a technique that can analyze electrons’ responses to light to discover previously hidden details about their geometry.

The role of Kagome metal in this breakthrough

kagome metal has a unique lattice structure similar to interlocking triangles. This unique pattern affects the way electrons are:

  • Move and transfer energy in the material.
  • Arrange synchronous patterns, similar to carefully choreographed dances.
  • It has superconducting properties, which can lead to energy-saving power grids and late electronic devices.
