We recently purchased an in situ heating holder from Hitachi and installed it in the aberration corrected STEM Hitachi HD2700. The heating temperature can increase up to 1200C. The in situ heating experiments performed in the aberration corrected STEM can allow you to directly observe the phase transformation, nanoparticle crystallization and growth, atomic cluster or single atom rippening, phase segregation, elemental homogenization, and many others at atomic scale. Currently we hold two types of heating chips w/ or w/o hole in thin SiNx membrane. But the hitachi company offer many selections of heating chips available to buy in small quantity i.e. 5/pk.
If you need to know anything more about the heating experiment or training in the STEM, please contact Mengkun Tian.
