In Situ and Ex Situ TEM Study of Lithiation Behaviours of Porous Silicon Nanostructures
In this work, we study the lithiation behaviours of both porous silicon (Si) nanoparticles and porous Si nanowires by in situ and ex situ transmission electron microscopy (TEM) and compare them with solid Si nanoparticles and nanowires. The in situ TEM observation reveals that the critical fracture diameter of porous Si particles reaches up to 1.52 μm, which is much larger than the previously r...
متن کاملEx situ Lift Out of PFIB Prepared TEM Specimens
Inductively coupled plasma sources are capable of producing Xe + ions for commercial focused ion beam (FIB) applications [1,2]. It should be no surprise that the longstanding Ga + FIB strategies for transmission electron microscopy (TEM) specimen preparation are directly applicable and transferrable to the plasma FIB (PFIB). Indeed, we showed a few years ago that the Xe + PFIB can produce elect...
متن کاملCoupling In Situ TEM and Ex Situ Analysis to Understand Heterogeneous Sodiation of Antimony.
We employed an in situ electrochemical cell in the transmission electron microscope (TEM) together with ex situ time-of-flight, secondary-ion mass spectrometry (TOF-SIMS) depth profiling, and FIB-helium ion scanning microscope (HIM) imaging to detail the structural and compositional changes associated with Na/Na(+) charging/discharging of 50 and 100 nm thin films of Sb. TOF-SIMS on a partially ...
متن کاملIn-situ TEM Study of Dislocation-Interface Interactions
In this chapter, we highlighted the in situ transmission electron microscope (TEM) observation of the interactions of dislocations with three types of interfaces: (i) twin boundaries in Cu; (ii) metallic interphase boundaries; and (iii) metal/ceramic interfaces. Interface structures, interface properties, and dislocation-interface interactions are characterized in a high-resolution TEM. These k...
متن کاملIn situ TEM ion irradiation and implantation effects on Au nanoparticle morphologies.
Energetic heavy and light ion effects on gold nanoparticles were probed by irradiating 20 and 60 nm diameter nanoparticles with either 3 MeV Cu(3+) or 10 keV He(+) ions in situ inside of a transmission electron microscope. Both ion species caused sintering, agglomeration, and ablation of the nanoparticles via sputtering, although at different rates.
