Toward Tunable Magnetic Dirac Semimetals: Mn Doping of Cd3As2

Advanced Functional Materials, EarlyView.
Dilute magnetic doping of topological semimetals offers a pathway to tune the topological phase via time reversal symmetry breaking. This is achieved by alloying the Dirac semimetal Cd3As2 with Mn via molecular beam epitaxy. Magnetotransport measurements provide preliminary evidence of changes to the electronic structure consistent with the emergence ...

AUPEC 2006: 16th Australasian Universities Power Engineering Conference

, 2006
[Abstract]: Australian Standard AS 4777.2-2005, section 4.9 imposes limits on DC injection into the AC network by grid connected inverters. One way to ensure that this requirement is met is to use a power transformer as interface between the output of ...

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

A direct-conversion mixer with DC-offset cancellation for IEEE 802.11a WLAN receiver

, 2006
A DC-offset cancellation scheme in the 5GHz direct-conversion receiver compliant with IEEE 802.11a wireless LAN standard is described in this paper. It uses the analog feedback loop to eliminate the DC-offset at the output of the double-balanced mixer ...

Optimal choice of the number of even harmonics demodulated from the excitation current of a sensor for precise dc voltage component detection in low voltage distributive grid as a strategy for suppression of the systematic error due to the grid voltage fluctuation [PDF]

Zbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2018
This paper addresses the problem of suppression of a systematic measurement error during the detection of a parasitic DC voltage component, superimposed to an AC voltage. As a sensor the toroidal transformer is employed.

Orbital Geometry‐Governed Response of Pressure‐Tunable Quantum Defects in hBN

Advanced Functional Materials, EarlyView.
Defects in hBN act as ultrasensitive quantum manometers when the energy of the intradefect optical transitions is modified by lattice compression. The orbital geometry of the electron wave functions governs how electron hopping and Coulomb interactions react uniquely to the reduction of the van der Waals gap and in‐plane compression, leading to robust ...
