Silicon-based Intermediate-band Infrared Photodetector realized by Te Hyperdoping
Mao Wang, Eric García-Hemme, Yonder Berencén +7
Si-based photodetectors satisfy the criteria of low-cost and environmental-friendly, and can enable the development of on-chip complementary metal-oxide-semiconductor (CMOS)-compat…
p-type codoping effect in (Ga,Mn)As: Mn lattice location versus magnetic properties
Chi Xu, Chenhui Zhang, Mao Wang +7
In the present work, we perform a systematic investigation on p-type codoping in (Ga,Mn)As. Through gradually increasing Zn doping concentration, the hole concentration increases,…
Hole compensation effect in III-Mn-V dilute ferromagnetic semiconductors
Chi Xu, Mao Wang, Ye Yuan +3
A systematic study of hole compensation effect on magnetic properties, which is controlled by defect compensation through ion irradiation, in (Ga,Mn)As, (In,Mn)As and (Ga,Mn)P is p…
Thermal stability of Te-hyperdoped Si: Atomic-scale correlation of the structural, electrical and optical properties
Mao Wang, R. Hubner, Chi Xu Yufang Xie +6
Si hyperdoped with chalcogens (S, Se, Te) is well-known to possess unique properties such as an insulator-to-metal transition and a room-temperature sub-bandgap absorption. These p…
Epitaxial Mn5Ge3 (100) layer on Ge(100) substrates obtained by flash lamp annealing
Yufang Xie, Ye Yuan, Mao Wang +7
Mn5Ge3 thin films have been demonstrated as a promising spin-injector material for germanium-based spintronic devices. So far, Mn5Ge3 has been grown epitaxially only on Ge (111) su…
Defect-induced exchange bias in a single SrRuO3 layer
Changan Wang, Chao Chen, Ching-Hao Chang +9
Exchange bias stems from the interaction between different magnetic phases and therefore it generally occurs in magnetic multilayers. Here we present a large exchange bias in a sin…
Tunable disorder and localization in the rare-earth nickelates
Changan Wang, Ching-Hao Chang, Angus Huang +13
The rare-earth nickelates are a rich playground for transport properties, known to host non-Fermi liquid character, resistance saturation and metal-insulator transitions. We report…
Electronic phase separation in insulating (Ga,Mn)As with low compensation: Super-paramagnetism and hopping conduction
Ye Yuan, Mao Wang, Chi Xu +6
In the present work, low compensated insulating (Ga,Mn)As with 0.7% Mn is obtained by ion implantation combined with pulsed laser melting. The sample shows variable-range hopping t…
Carrier driven antiferromagnetism and exchange-bias in SrRuO3/CaRuO3 heterostructures
Parul Pandey, Ching-Hao Chang, Angus Huang +7
Oxide heterostructures exhibit a rich variety of magnetic and transport properties which arise due to contact at an interface. This can lead to surprising effects that are very dif…
Towards diluted magnetism in TaAs
Yu Liu, Zhilin Li, Liwei Guo +10
Magnetism in Weyl semimetals is desired to investigate the interaction between the magnetic moments and Weyl fermions, e.g. to explore anomalous quantum Hall phenomena. Here we dem…
Interplay between localization and magnetism in (Ga,Mn)As and (In,Mn)As
Ye Yuan, Chi Xu, René Hübner +6
Ion implantation of Mn combined with pulsed laser melting is employed to obtain two representative compounds of dilute ferromagnetic semiconductors (DFSs): Ga1-xMnxAs and In1-xMnxA…
Monovacancy paramagnetism in neutron-irradiated graphite probed by C NMR
Z. T. Zhang, C. Xu, D. Dmytriieva +6
We report on the magnetic properties of monovacancy defects in neutron-irradiated graphite, probed by C nuclear magnetic resonance spectroscopy. The bulk paramagnetism of th…
