关于“Bi $_2$ Sr $_2$ CaCu $_2$ O $_{8+δ}$:自加热的结尺寸依赖性”的评论[物理学修订版B 73,224501(2006)]

Comment on `Intrinsic tunnelling spectroscopy of Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$: The junction-size dependence of self-heating'[Phys.Rev.B 73, 224501 (2006)]

V. N. Zavaritsky

摘要:

最近的PRB 73,224501(2006),此后称为参考文献\cite{0},声称自加热随着样品面积的减少而减少,并声称在亚微米“台面”中识别ITS的内在原因。我将证明这种说法缺乏根据。我将进一步证明,同一个$R(T)$和无参数牛顿冷却定律定量描述了丰富多样的ITS行为所采取的参考\cite{0}以上和以下$T_c$在浴温度跨越150 K。因此,这一发现提供了强有力的证据,支持加热作为参考文献\cite{0}促进的“本征隧穿光谱”(ITS)的原因。

英文摘要:

The recent PRB 73, 224501 (2006) henceforth referred as Ref.\cite{0} asserts that self-heating decreases with sample area reduction and claims to identify the intrinsic cause of ITS in submicrometre `mesa'. I will show that this assertion lacks substantiation. I will further demonstrate that one and the same $R(T)$ and the parameter-free Newton's Law of Cooling describe quantitatively a rich variety of ITS behaviours taken by Ref.\cite{0} above and below $T_c$ at bath temperatures spanned over 150K. Thus this finding presents strong evidence in favour of heating as the cause of the `intrinsic tunnelling spectra' (ITS) promoted by Ref.\cite{0}.
