第十五章 寒食散
虎儿自然听说过五石散,抑或是寒食散。在何晏的许多著述里,寒食散被一次次地提及
;他抄过何晏、索靖的碑帖,里面有些地方便赫然写着寒食的妙处。可是家人曾告诫道
,寒食散乱性,因此未加冠的孩子是不许碰这种药的。因为家人绝口不提,他竟不知道
这药在外面其实多么流行,也万万没有想到,在今天的宴会上,寒食散竟会被呈送到自
己的眼前来。
虎儿觉得自己被逼到了墙角:究竟尝不尝寒食散,所有的人,包括舅舅,都在等着他当
场做一个抉择。他很不习惯这样的场面,不知道该怎么周旋应付,下意识地咬着嘴唇,
一双眼睛求救似地朝王武子望去。
王武子拍了拍他的肩膀,微笑道:“孙太守说得没错。寒食散性热,本是治伤寒的奇药
。体弱的人,吃一点儿进补是有利无害的。再说,”他眨了眨眼睛,“我也保证不会让
你母亲知道。”说着便从锦盒中拿出一粒药丸,用小金刀切去一半,放到了虎儿的手里。
虎儿只得接了,学着众人的样子,把药丸含在嘴里,喝了一口温热的药酒。
那粒红色的小丸子,一接触到舌头,立刻散发出奇苦无比的滋味儿,让他一下子想起从
小到大吃过的最苦的草药——都还不如眼下的这粒苦。这是一种让人不安的味道,苦里
带着奇怪

请教一下,什么是flat band voltage? 从字面不好理解啊。。另外这个voltage 是应
该大好还是小好?应该多稳定?谢谢咯。

If you refer to flat band voltage in MOS/MOSFET, it is a negative voltage
applied between the metal and semiconductor to achieve flattening of the
bands.
It is determined by two factors: the work function difference between metal
and s/c and charges in the oxide. You may find the formula for calculation
in any fundamental mosfet books.
If you're targeting for a normally-off MOSFET(Vth>0), it's better to have a
flat band voltage of smaller absolute value. For example, you may choose a
gate contac

谢谢啊。在问一下什么叫"achieve flattening of the bands"?让band offset变成0?

对于基本概念,随便找一本应该都差不多。当然比较全面和经典的就是 Sze 的physics
of semiconductor devices.
