Abstract

Ketidakstabilan struktur kekisi persegi tertekuk monolayer pada SnS telah diuji menggunakan tiga indikasi yaitu energi ikat antar lapisan, dispersi phonon serta dinamika molekular pada suhu tetap. Sebagai pembanding telah diuji pula ketiga indikasi tersebut pada struktur SnS blackphosphorene yang telah terbukti stabil. Pengujian kestabilan ini telah dilakukan menggunakan software bebas lisensi yaitu OpenMX dan Alamode.

Kata Kunci : kestabilan struktur, energi ikat antar layer, dispersi phonon, dinamika molekular, SnS persegi tertekuk monolayer, alamode, openmx.

Abstract
The stability of monolayer buckled-square lattice of SnS has been studied based on three indicators; inter-layers bond energy, phonon dispersion, and molecular dynamics in constant temperature. As a comparison, those three indicators also have been studied for blackphosphorene SnS structure which the stability has been proved. This study of stability has been done using two kind freeware: OpenMX and Alamode.

Keywords: structure stability; interlayers bond energy; phonon dispersion; molecular dynamics; monolayer buckled-square lattice SnS; alamode; openmx
