Unraveling the Catalytic Effect of Hydrogen Adsorption on Pt Nanoparticle Shape-Change
Cameron J. Owen, Nicholas Marcella, Yu Xie +4
The activity of metal catalysts depends sensitively on dynamic structural changes that occur during operating conditions. The mechanistic understanding underlying such transformati…
InAs nanocrystals with robust p-type doping
Lior Asor, Jing Liu, Yonatan Ossia +4
Robust control over the carrier type is fundamental for the fabrication of nanocrystal-based optoelectronic devices, such as the p-n homojunction, but effective incorporation of im…
From Impurity Doping to Metallic Growth in Diffusion Doping: Properties and Structure of Ag Doped InAs Nanocrystals
Yorai Amit, Yuanyuan Li, Anatoly I. Frenkel +1
Tuning of the electronic properties of pre-synthesized colloidal semiconductor nanocrystals (NCs) by doping plays a key role in the prospect of implementing them in printed electro…
Multi-modal Spectroscopic Study of Surface Termination Evolution in Cr2TiC2Tx MXene
James L. Hart, Kanit Hantanasirisakul, Andrew C. Lang +6
Control of surface functionalization of MXenes holds great potential, and in particular, may lead to tuning of magnetic and electronic order in the recently reported magnetic Cr2Ti…
A Synchrotron in the TEM: Spatially Resolved Fine Structure Spectra at High Energies
James L Hart, Andrew C Lang, Yuanyuan Li +3
Fine structure analysis of core electron excitation spectra is a cornerstone characterization technique across the physical sciences. Spectra are most commonly measured with synchr…
X-ray induced persistent photoconductivity in Si-doped AlGaAs
Yeong-Ah Soh, G. Aeppli, Frank M. Zimmermann +2
We demonstrate that X-ray irradiation can be used to induce an insulator-metal transition in Si-doped AlGaAs, a semiconductor with {\it DX} centers. The excitatio…
