Subject: [labnetwork] Customs and Duty
Message-ID: <CAOsRozK6K59UBLfiSFipJsT+=PS=j+MWJS4FEPTYuMSfS+=-ZA@mail.gmail.com>
Greetings,
This email is to request any advice on customs and duty exemption for
research equipment and supplies. Has anyone found a system that works?
This has become a significant cause for concern during the past year or
so. I have been in a purchasing role since 2008 and I have never
encountered such inconsistencies, even with orders from the same supplier.
I fear we are unnecessarily paying fees that could possibly be exempt, but
haven't been able to find any straightforward answers.
Any help would be greatly appreciated.
Kind regards,

Subject: [labnetwork] Question regarding amorphous Si deposition
Message-ID: <CAFAjiqDPgEEwuTR+LpMwYHqXYBEvZFATTF+W2TCYCL1V1cD4iw@mail.gmail.com>
Hi everyone,
Is there a way to deposit thick amorphous Si on several micrometres
scale(~5um or above) but with a low processing temperature (<150 deg C)?
PECVD is one possibility but the typical operating substrate temperature is
too high (>200 deg C) which will destroy our device.
Best regards,

Hi Zhu,
I have done 1 ?m films of amorphous Si in an e-beam evaporation chamber. I
had some issues with delamination when I was growing it. What I had to do
was to slow down the rate of deposition. Unfortunately that means you have
longer deposition times, therefore more exposure to radiative heat from
the source. In that chamber we did not have a thermocouple on the sample
holder and we didn't know what was the max temperature reached.
It may be worth trying if you have a way to measure T and see if you can
keep that in check by growing it in stages with cooling times in between.
I hope this helps,
Cheers,
Carlos
