Because of their loosely bound electrons, electrides offer physical properties useful in chemical synthesis and electronics. For these applications and others, nanosized electrides offer advantages, but to-date no electride has been synthesized as a nanomaterial. We demonstrate experimentally that Ca2N, a layered electride in which layers of atoms are separated by layers of a 2D electron gas (2DEG), can be exfoliated into two-dimensional (2D) nanosheets using liquid exfoliation. The 2D flakes…

Sc2C, a 2D Semiconducting Electride.
Electrides are exotic materials that typically have electrons present in well-defined lattice sites rather than within atoms. Although all known electrides have an electropositive metal cation
Electrons on the surface of 2D materials: from layered electrides to 2D electrenes
The unique properties of 2D materials have motivated the discovery of new atomically thin materials that push the boundaries of synthetic design and device performance. One new class of 2D materials
The ionic versus metallic nature of 2D electrides: a density-functional description.
D density-functional theory is used to investigate exfoliation and interlayer sliding of the only two experimentally known 2D electrides, and it is conjecture that the metallic nature of the interstitial electrons allows the atomic layers to move relative to each other without significantly altering the interlayer binding.
Switchable two-dimensional electrides: A first-principles study
Electrides, with excess anionic electrons confined in their empty space, are promising for uses in catalysis, nonlinear optics, and spin electronics. However, the application of electrides is limited
MXene Phase with C3 Structure Unit: A Family of 2D Electrides
A new structural phase is discovered for M2CO2 MXenes with M = Sc, Y, La, Lu, Tm, and Ho. The hexagonal carbon layer sandwiched between M atoms, typical for MXenes, is transformed into C3 trimers
How Many Electrons Holds a Molecular Electride?
Electrides are very peculiar ionic compounds where electrons occupy the anionic positions. In a crystal lattice, these isolated electrons often group forming channels or surfaces, furnishing
Synthesis and Electronic Structure of a Crystalline Stack of MXene Sheets
Despite the interest in MXenes in the last decade, all of the MXenes reported have a random mixture of surface terminations (-O, -OH, -F). In addition, restacked films have turbostratic disorder and
Theoretical Descriptors of Electrides.
Eight common theoretical descriptors of electrides are surveyed for their efficacy in identifying these materials and density-based descriptors such as the electron localization function (ELF) and localized-orbital locator (LOL) are shown to be the most consistently reliable.
How Many Electrons Does a Molecular Electride Hold?
This paper analyzes the non-nuclear attractor (NNA) and the surrounding region of nine molecular electrides to determine the number of isolated electrons held in the electride and classified them according to the most likely number of electrons that the NNA can find.

Enhanced N2 dissociation on Ru-loaded inorganic electride.
Electrides, i.e. salts in which electrons serve as anions, are promising materials for lowering activation energies of chemical reactions and Splitting of N2 is promoted by a combination of the strong electron donating power of C12A7:e(-), ability of Ru to capture N2, polarization of Ru clusters, and electrostatic interaction of negatively charged N species with the surface cations.
