that bug is too obvious.
The other several parts are not reasonable too.
1. The country can easyly defeat ZJ bu limisted the meterial. It is too easy
to think about it without too much thinking, and so easy to limit to
certain people who get/use the meterial.
2. why ZJ hats everyone, and try to kill and revenge the country. The book
try to explain it, but not reasonable.
3. ZJ always have a good luck in the fight Without those luck , the ZJ will

来自主题: _Stockcafeteria版 - zz: 估计明天大阳棒,后天出大阴棒
由于aapl crush er,TXN beat 了er,市场反应很好,盘后都涨了不少。明天没什么意
外应该是大阳棒。
后天估计是大阴棒,原因如下:
1。股市不可能一直长,猛涨两天后很有可能有一个pullback,尤其是在10000点的高位
下。
2。周三盘前wfc 和Boeing 出er。wfc 是全美第一大mortage bank,公司主力在ca,而
ca 的失业率非常高,foreclosure rate 在全美排名前三,从bac 和jpm er 来看,wfc
er 不会好。
boering 则由于航空业的低迷,不少预定的飞机都被cancel 了,estimate eps 都是-$
2.12, er 也不会好。
就我个人来说,我手上6 只股票全都是energy 和basic meterial。周三basic
meterial的indicator fcx盘前出er,fcx 最近3 个月涨了42%,很有可能出现sell on
news,我不想也不敢赌er。所以没什么意外我明天会逢高出空所有holding,全仓cash
,周三盘中逢低买进。

寻找美国房地产开发合伙人
本人背景介绍:文科男,07年毕业于某top MBA,金融方向,遂即去了一家大型商业银
行的regional branch个人信贷部。2009年,将老婆(现在是CPA)孩子留在美国,和合
伙人回国组建了一家针对房地产和展会的高科技公司,2014年公司销售业绩900W RMB,
员工45人,代理商20家。今年年初,将公司的80%的股权转让,自己准备进军美国房地
产。
我们为什么要在美国开发房地产?
1.以我生活的国内二线城市为例,房地产正在崩盘的节奏,用业内人的一句话说"以前
做开发的房地产老板是大老板,现在有项目在进行的房地产老板已经不再是老板了。"
具体原因不说了,参考mit现在的头条 http://www.mitbbs.com/article_t/Travel/31824577.html (这里的观点99%和我一样,我甚至觉得是哪位仁兄听我的高论然后自己写出来的) 由于公司业务关系,我接触大量的房地产圈人脉,有几个非常好的大哥房地产老板。这些人现在几乎都在停滞阶段,中国最好的房地产黄金期已经去了,原来在房地产形成原始积累的国内土豪们纷纷在找新的机会。

来自主题: EE版 - Si .vs. other meterials
I find this could be an interesting topic to talk about.
The competition between Si and other materials, particularly
III-V compounds is really interesting.
When III-V compounds first come to people's mind, lots of them
think they will substitute Si since their characteristics
are much better than Si in many ways, such as high freq
response, high gain, low loss, etc.
The most important drawback of III-V compounds is fabrication.
And that's just the advantage of Si based device.

GaAs dominates the microwave circuit and devices in these years.
Because Si technology is well developed and fabrication cost is low, many
people are still trying to extend silicon circuit to higher frequency range.
Though MMIC is fabricated mostly with GaAs, some silicon based MMIC designs
at S or L band are coming up. But they are still in lab. The atracting thing
of these silicon based designs is their lumped element design at this
frequency. This means they can be built much smaller than dis

No, the two fabrication precesses are quite different.
GaAs for example has no good passivation layer unlike SiO2 for Si.
So MOS structure is difficult to achieve on GaAs.
For III-V integrate circuit, MESFET is dominant.
In addition, III-V materials are less thermally-stable than Si, this also
lead to quite processing techinque.
by the way, I have to mention compound are not alloy as you said, although
GaAs is relatively more difficult than Si to get, now good quality GaAs
crystal are available

来自主题: EE版 - Si .vs. other meterials
As far as I know, the cost of GaAs wafers are much more
than silicon wafer, which makes them less widely used even
that they have higher electron mobility.
Also, at very small dimension, the mobility won't be the
limiting factor
as velocity saturation will play the limiting role. At this
condition,
the advantage of III-V over Si will be very small.
Another reason making III-V less attractive in ULSI is that
SiGe is attracting
much attention from the industry, especially IBM. Ge has
also a high m

No, GaAs wafer is not so expensive compared with SiC, for example.
, usually 3 inch with decent quality costs about 3-5 hundreads bucks.actually
quite cheap.In addition, it is worth noting that the cost of substrate is
quite small in the total of chip fabrication. <2%? The main obstable is its
sophisticated processing. for example, usually 1/3 cost of fabrication is
lithography.
No, the saturation velocity of electron in GaAs is much higher than in Si.

CMP or post-packaging belongs to processing.
If only for the cost of substrate, it is really very small.
You are both not right.
Actually the satuation velocity of GaAs is only several times lager than Si.
The fact is the critical field for the electron to reach saturation velocity
in the two materials is quite different. For GaAs, about 4kV/cm, but for Si,
it needs >20KV/cm.
The package density of GaAs devices is quite low compared with Si. he means
MMIC.

It should be aerogel. Yes, it's an amazing meterial. I even could hardly see
it, when I opened the package from a Japanese company. It has already been
used for certain purposes, e.g. the Cherenkov detector for high energy
phyiscs. However, it is believed it has a wide potential applications for
various aspects.
