2. it may be necessary to get poly pin structure if the poly quality is not
good. The question is, why nobody work on this pin structure
3. actually, you can grow a-Si first, and crystallize using say SPC.
4. still there are many issues for the tandem cell, like current match.
complex processing et al
5. personally, I think poly-si thin film is the way. you may not agree, but

我现在用probe和示波器做测试的时候感觉检测到的电信号是probe或导线在外加交变磁

PZT thin film有1um, 不知道能产生多大的电压信号,请问有哪些方法可以检测到电信

w********h 发帖数: 12367 | 6 Generally they use ellipsometry to measure thin film. |
|
c*s 发帖数: 2145 | 7 it uses the different refractive index between substrate and your film...
more details, i dunt know.
But it requires that you know the approximate thickness beforehand, then it
will try-and-error and give you the value... |

l*****o 发帖数: 82 | 8 If some polymer solution( such as PMMA in isopropenol) is spin-coated
on a Si wafer at spinning speed V rpm, how to calc the thickness distribution
of coated polymer film?
Anyone can give a hint? |
|
a***n 发帖数: 578 | 9 all I should tell you is to read more papers. hehe.
Your problem is quite similiar to the molecular beam expitaxy simulation.
in MBE, one tech is to use molecular beam to hit on a rotating plate and thus
grow a crystal thin film on that plate.
The simulation in MBE can be difinitely used in your model. MBE is more
complicated.
I don't know where to find that paper right now. That is what I read years
ago. But difinitely I can solve it. hehe. If you want me to set up a
simulation software for you |
|
l*****o 发帖数: 82 | 10 I don't think it's similar to MBE problem. (I did work on it for 3
years, and even build a special MBE machine^_^) Because when the plate
rotates, the speed is much slow than spin-coating, especially compared
with the low depositing rate. Also, the mobility of those atom clusters
is very low, they can only move around a certain area. The reason why
ppl using rotating plate is make the crystal film as uniform as possible.
otherwise the center will be much thicker than edge. But in spin-coating

a***n 发帖数: 578 | 11 hey. is this what you want? keke. it IS simpler than MBE simulation. My offer
is still there. xixi. 10K for writing this simulation tool.
This method is solving 1 dimension kinetic equation simpler than what I
thought.
the rotating speed is presenting as extra force in the system. The continum
model is used to describe the polymer.

f*****j 发帖数: 1 | 15 You may pour your solution in a Teflon plate and allow the solution to dry
very slowly. You should calculate what thickness is needed and
correspondingly what what concentration. Anyway, be sure to use Teflon plate
and it allows you to peel the film easily and to get uniform thickness
relatively. Good luck. |

The problem actually is that both oleic acid-capped PbS and butylamine
exchanged PbS form small aggregates in octane. I expected those QDs can
completely dissolve in octance. But it did not happen. The films I got were
continous but with many tiny domains of aggregates.
I did everything from washing to exchange to spin coat in air. But with OA
the capping reagent, the QDs shoudl be readily dissolve/disperse in a
nonpolar solvent even PbO forms |

A lot of installers recommend Suntek nowadays, not Xpel or others. But

x*b 发帖数: 5723 | 44 稍微补充一下,我不是只选Xpel Ultimate,我是强调和Suntek比。目前市面上最顶级
的Clear Bra其实有2款,分别是ClearGuard Nano和Xpel Ultimate。Suntek的膜比上面
两个薄25%,保护性能不如它们。但是就是因为薄,所以相对更容易install because
it's easier to stretch,installer当然也就更喜欢。再加上进价相对最低,对于新
一点的店自然会作为首选。
ClearGuard Nano就是出Spectra PhotoSync Tint这个公司出的,叫Prestige Film
Technologies,但是官网上Nano这个型号还没出来,所以你看不到。他们家的各种膜都
