Abstract
Proposed are a layered Group III-V arsenic compound, a Group III-V nanosheet that may be prepared using the same, and an electrical device including the materials. There is proposed a layered compound having a composition represented by [Formula 1] Mx-mAyAsz (Where M is at least one of Group I elements, A is at least one of Group III elements, x, y, and z are positive numbers which are determined according to stoichiometric ratios to ensure charge balance when m is 0, and 0<m<x).
Claims17
A layered compound having a composition represented by Formula 1 below:
- Mx-mAyAsz [Formula 1]
- wherein M is at least one of Group I elements, A is at least one of Group III elements, x, y, and z are positive numbers which are determined according to stoichiometric ratios to ensure charge balance, and wherein the m is greater than 0 and satisfies 0.1≤m≤0.9×.
A nanosheet comprising a composition represented by Formula 1 below and two or more two-dimensional layers, the nanosheet being prepared through a physical or chemical peeling method:
- Mx-mAyAsz [Formula 1]
- wherein M is at least one of Group I elements, A is at least one of Group III elements, x, y, and z are positive numbers which are determined according to stoichiometric ratios to ensure charge balance, and wherein the m is greater than 0 and satisfies 0.1×≤m≤0.9×.
The nanosheet according to claim wherein the M is Na, K or a combination thereof.
