Zn-doped P-type InAs Nanocrystal Quantum Dots
Lior Asor, Jing Liu, Shuting Xiang +3
Doped heavy metal-free III-V semiconductor nanocrystal quantum dots are of great interest both from the fundamental aspects of doping in highly confined structures, and from the ap…
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…
Anisotropy in BaFe2Se3 single crystals with double chains of FeSe tetrahedra
Hechang Lei, Hyejin Ryu, Anatoly Frenkel +1
We studied the anisotropy in physical properties of Ba1.00(4)Fe1.9(1)Se3.1(1) single crystals. BaFe2Se3 is a semiconductor below 300 K. Magnetization measurements show that there i…
Evidence for short range orbital order in paramagnetic insulating (Al,V)_2O_3
P. Pfalzer, J. Will, A. Nateprov +6
The local structure of (Al_0.06V_0.94)_2O_3 in the paramagnetic insulating (PI) and antiferromagnetically ordered insulating (AFI) phase has been investigated using hard and soft x…
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…
