Abstract

The elastic, mechanical, thermodynamic, and ultrasonic properties of Mg2Y (Y=Si, Ge, and Sn) composite semiconducting nanomaterials were investigated by Lennard-Jones potential analysis, which evaluated elastic coefficients in second and third order, and as per our investigation and comparative evaluation from other research works, we can conclude that for the higher orders, the elastic constants in the initial parameter increase little, but for the successor, it will barely increase towards Sn from Si with Mg2. Further, the elastic constants have been used to examine the mechanical characteristics of hexagonal Mg2Y (Y=Si, Ge, and Sn) nanomaterial via its Poisson's ratio, Young’s modulus, bulk modulus, and other relative thermodynamic properties. Here the bulk modulus is presenting an increase in comparison to their bulk moduli. The nanomaterial composition is the same from Si, Ge, and Sn and from here the calculated G/B ratio of 0.976 indicates that Mg2Y (Y=Si, Ge, and Sn) is primarily composed of ionic bonds. When computing the thermal conductivity (kmin) at different compositions, the computation outcomes have been satisfactory. As composition changes from Si, Ge, and Sn, the thermal conductivity of compositions Mg2Y (Y=Si, Ge, and Sn) increases continuously with a steady state of hardness indication. This composition, which compounds Mg2Si, Mg2Ge, and Mg2Sn has also been tested for attenuation and composition dependent ultrasonic velocities and depicted in their relative responses. This composition is at its purest at initial attenuation, and its ductility is indicated by its lowest attenuation.

Mg2Y (Y =Si, Ge ve Sn) Yarı İletken Nanomalzemelerde Elastik, Mekanik ve Termoelektrik Özelliklerin Karşılaştırmalı Analizi

Abstract

Mg2Y (Y=Si, Ge ve Sn) kompozit yarı iletken nanomalzemelerin elastik, mekanik, termodinamik ve ultrasonik özellikleri, elastik katsayılarını ikinci ve üçüncü dereceden değerlendiren Lennard-Jones potansiyel analizi ile araştırılmıştır ve bizim araştırmamıza ve diğer araştırma çalışmalarından elde edilen karşılaştırmalı değerlendirmelere göre, daha yüksek dereceler için başlangıç ​​parametresindeki elastik sabitlerinin çok az arttığı, ancak halef için Si'den Mg2'ye doğru Sn'ye doğru zar zor artacağı sonucuna varabiliriz. Dahası, elastik sabitleri, Poisson oranı, Young modülü, hacim modülü ve diğer bağıl termodinamik özellikleri yoluyla hekzagonal Mg2Y (Y=Si, Ge ve Sn) nanomalzemesinin mekanik özelliklerini incelemek için kullanılmıştır. Burada hacim modülü, hacim modüllerine kıyasla bir artış göstermektedir. Nanomalzeme bileşimi Si, Ge ve Sn'den aynıdır ve buradan hesaplanan 0,976'lık G/B oranı, Mg2Y'nin (Y=Si, Ge ve Sn) öncelikle iyonik bağlardan oluştuğunu gösterir. Farklı bileşimlerde termal iletkenlik (kmin) hesaplanırken, hesaplama sonuçları tatmin edici olmuştur. Bileşim Si, Ge ve Sn'den değiştikçe, Mg2Y (Y=Si, Ge ve Sn) bileşimlerinin termal iletkenliği, sabit bir sertlik göstergesi durumuyla sürekli olarak artar. Mg2Si, Mg2Ge ve Mg2Sn'yi bileşik haline getiren bu bileşim, zayıflama ve bileşime bağlı ultrasonik hızlar için de test edilmiş ve bunların bağıl tepkilerinde tasvir edilmiştir. Bu bileşim, ilk zayıflamada en saf halindedir ve sünekliği en düşük zayıflamasıyla gösterilir.
