Summary
This study explores one-dimensional (1D) atomic chains of elemental metals, revealing buckled structures and identifying three semiconducting chains. The findings guide the synthesis and characterization of these novel low-dimensional materials.
Area of Science:
- Materials Science
- Condensed Matter Physics
- Computational Chemistry
Background:
- Low-dimensional materials offer unique properties for advanced technologies.
- Research has primarily focused on two-dimensional (2D) materials.
- Recent advances enable exploration of one-dimensional (1D) materials.
Purpose of the Study:
- To systematically investigate the properties of 40 non-magnetic 1D atomic chains of elemental metals.
- To explore their geometry, energetics, elasticity, and electronic structure.
- To provide a foundation for experimental synthesis and characterization.
Main Methods:
- Density-functional theory (DFT) simulations were employed.
- Molecular dynamics (MD) simulations assessed dynamical stabilities.
- Chain pulling simulations investigated straightening dynamics.
Main Results:
- Nearly all 1D chains exhibit a buckled ground state.
- Three chains (Cd, Hg, Sr) were identified as semiconducting with an electronic gap.
- 26 out of 40 chains demonstrated thermodynamic stability at 100 K.
- Transition metals retain significant cohesive energy in 1D.
Conclusions:
- The study provides a comprehensive analysis of 1D atomic metal chains.
- Identified stable and semiconducting chains offer pathways for new material development.
- The findings serve as a guide for experimental efforts in 1D material synthesis.

Metallic Solids
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 malleability. Many...

Theory of Metallic Conduction
The conduction of free electrons inside a conductor is best described by quantum mechanics. However, a classical model makes predictions close to the results of quantum mechanics. It is called the theory of metallic conduction.
In this theory, Newton's second law of motion is used to determine the acceleration of an electron in the presence of an applied electric field. Then, its velocity is expressed via this acceleration.

Periodic Classification of the Elements
The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...
Bonding in Metals
Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.
Properties of Transition Metals
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.
Fermi Level
The Fermi-Dirac function is represented by an S-shaped curve indicating the probability of an energy state being occupied by an electron at a given temperature. The Fermi level is the energy level at which there is a fifty percent chance of finding an electron, and it is positioned between the lower-energy valence band and the higher-energy conduction band.
At absolute zero temperature, electrons fill all energy states up to the Fermi level, leaving upper states empty. As the temperature rises,...
