TRANSMISSION ELECTRON MICROSCOPY OF SPONTANEOUS TIN (SN) WHISKER GROWTH UNDER HIGH TEMPERATURE/HUMIDITY STORAGE
(IEEE, 2008-12-09)
The present work is devoted to characterize the microstructures of Sn/Cu lead-frame attached on the printed circuit board (PCB) and of tin-whiskers formed on the Sn-surface after exposure under 85C/85 %RH for 1000 and ...
TIN WHISKER FORMATION ON A LEAD-FREE SOLDER ALLOY STUDIED BY TRANSMISSION ELECTRON MICROSCOPY
(IEEE, 2006-12-06)
Tin whiskers grown on a Sn/Cu-plated Polyimide (PI)-flexible substrate are a serious problem in electronic industrial application, because the whiskers lead to catastrophic electrical short circuit failures. Here, we report ...
MICROSTRUCTURES OF MGB2 /FE TAPES FABRICATED BY AN IN SITU POWDER-IN-TUBE METHOD USING MGH2 AS A PRECURSOR POWDER
(IOP, 2006-01-04)
Microstructures of MgB2/Fe tapes fabricated by an in situ powder-in-tube method using MgH2 as a precursor powder have been studied by means of x-ray diffraction and analytical transmission electron microscopy combined with ...
CHANGES IN MICROSTRUCTURE OF AL/ALN INTERFACE DURING THERMAL CYCLING
(The Japan Institute of Metals and Materials, 2008-12-01)
Changes in the microstructure of the interface between an Al layer and an AlN plate during thermal cycling was studied to clarify the fracture mechanism of the Al/AlN interface. Observation of the interface with an ultra-sonic ...
RELATIONSHIP BETWEEN MICROSTRUCTURE AND JC PROPERTY IN MGB2/Α-AL2O3 FILM FABRICATED BY IN SITU ELECTRON BEAM EVAPORATION
(IOP, 2005-08-09)
A transmission electron microscopy (TEM) study has been carried out on an MgB2/α-Al2O3 film that exhibits the typical property of critical current density (Jc) under magnetic fields. The MgB2 layer of 300 nm in thickness ...
EFFECTS OF HEAT TREATMENTS ON MICROSTRUCTURE FORMATION IN MGB 2 /YSZ/HASTELLOY FILM
(2005-06)
Annealing processes in MgB2 films deposited on yttria-stabilized zirconia (YSZ)-buffered Hastelloy substrates were studied by transmission electron microscopy. The MgB2 films with Mg-rich compositions were fabricated at room ...
ELECTRON MICROSCOPY OF MGB2 THIN FILM ON YSZ-BUFFERED HASTELLOY
(Elsevier, 2004-06-11)
In order to understand the relationship between the microstructures and superconducting properties of MgB2 films, analytical TEM observations have been carried out. The films were fabricated by a KrF excimer laser deposition ...
TRANSMISSION ELECTRON MICROSCOPY ANALYSIS OF C4H4S-doped MgB2 TAPES
(IOP, 2008)
It has been reported that doping with aromatic hydrocarbons in an in situ powder-intube
fabrication process of MgB2 tapes is effective for increasing the critical current density (Jc) under magnetic fields. In this study, ...
REMOVING FOCUSED ION-BEAM DAMAGES ON TRANSMISSION ELECTRON MICROSCOPY SPECIMENS BY USING A PLASMA CLEANER
(OXFORD Academic, 2006-03-01)
A plasma cleaner is usually used for removing carbonaceous debris from a specimen and preventing contamination during transmission electron microscopy (TEM) imaging and analysis. However, the plasma cleaner can be effectively ...
MBE FABRICATION OF MNX P NANOWHISKERS
(2008)
MnP and MnP nanowhiskers have been grown by molecular-beam epitaxy (MBE)
technique on InP(100) and GaAs(111)B substrates. The catalyst-free growth of nanowhiskers
is found to be depended on the formation of Mn-based ...
