Recently, large challenge has been spent to realize high efficient thermal transistors. Outstanding properties of DNA make it as an excellent nano material in future technologies. In this paper, we introduced a high efficient DNA based thermal transistor. The thermal transistor operates when the system shows an increase in the thermal flux despite of decreasing temperature gradient. This is what called as negative differential thermal resistance (NDTR). Based on multifractal analysis, we could distinguish regions with NDTR state from non-NDTR state. Moreover, Based on dimension spectrum of the system, it is detected that NDTR state is accompanied by ballistic transport regime. The generalized correlation sum (analogous to specific heat) shows that an irregular decrease in the specific heat induces an increase in the mean free path (mfp) of phonons. This leads to the occurrence of NDTR.

近来，已经花费了巨大的挑战来实现高效的热晶体管。DNA的出色特性使其成为未来技术中极好的纳米材料。在本文中，我们介绍了一种基于DNA的高效热敏晶体管。尽管温度梯度降低，但系统显示的热通量增加时，热敏晶体管也会工作。这就是所谓的负差分热阻（NDTR）。基于多重分形分析，我们可以区分具有NDTR状态的区域和非NDTR状态的区域。此外，基于系统的尺寸谱，检测到NDTR状态伴随着弹道运输状态。广义相关和（类似于比热）表明，比热的不规则下降导致声子的平均自由程（mfp）增加。
