Abstract In this work, we have studied the entropy and specific heat of graphene as a function of temperature in the presence of an external magnetic field. In this regard, we have considered two regions of temperature such as low and high temperatures. Here, we have used a noncommutative phase-space to obtain electronic properties of graphene. The entropy is decreased with increasing the magnetic field for all temperatures. At high temperatures, the entropy approaches constant value (saturation value) for all used magnetic fields. The specific heat is reduced with increasing magnetic field at low temperatures and it shows a peak structure. As the magnetic field is increased, the peak shifts to higher temperatures and becomes broader in width. At high temperatures, the specific heat increases with enhancing magnetic field.

外磁场作用下石墨烯在低温和高温下的熵和比热

摘要 在这项工作中，我们研究了在外部磁场存在下石墨烯的熵和比热作为温度的函数。在这方面，我们考虑了低温和高温两个温度区域。在这里，我们使用非对易相空间来获得石墨烯的电子特性。对于所有温度，熵随着磁场的增加而降低。在高温下，所有使用的磁场的熵接近恒定值（饱和值）。在低温下，比热随着磁场的增加而降低，呈现出峰结构。随着磁场的增加，峰移到更高的温度并变得更宽。在高温下，比热随着磁场的增强而增加。
