Molecular-dynamics calculation of the thermal conductivity coefficient of the germanium single crystal

Abstract: The thermal conductivity coefficient of the germanium crystal lattice has been calculated by molecular dynamics simulation. Calculations have been performed for both the perfect crystal lattice and the crystal lattice with defects such as monovacancies. For the perfect germanium single crystal, the dependence of the thermal conductivity coefficient on the lattice temperature has been obtained in the temperature range of 150-1000 K. The thermal conductivity coefficient of the germanium lattice has been calculat… Show more

“…The development of modern electronics is associated with the search and development of new materials or the improvement of the properties of the existing ones. At present, a semiconductor material such as germanium is a promising material for creating various electronic devices and sensors such as diodes, triodes, dosimeter devices, transducers, Hall sensors, detectors of infrared radiation [1,2]. Technologies of strained germanium find their practical use in nanosized transistor structures and nanophotonics [3][4][5][6][7].…”

“…Another method for calculating the thermal conductivity coefficient, used today, is a molecular dynamics simulation of the crystal lattice. In article [15] germanium single crystals are considered as containing both an ideal lattice and defects (with the single vacancies). The drawback here is the enormous amount of computation due to the large number of atoms in the lattice (in [15] it was taken equal to 129600).…”

“…Розвиток сучасної мiкро-та наноелектронiки пов'язаний з розробкою нових напiвпровiдникових матерiалiв або вдосконаленням властивостей уже наявних. Такий напiвпровiдниковий матерiал, як германiй, на сьогоднi є перспективним матерiалом для створення на його основi рiзних електронних приладiв та сенсорiв, таких, як дiоди, трiоди, дозиметричнi прилади, тензодатчики, датчики Голла, детектори iнфрачервоного випромiнювання [1,2]. Технологiї напруженого германiю знаходять своє практичне використання в нанорозмiрних транзисторних структурах та нанофотонiцi [3][4][5][6][7].…”
