Surface-dominated conductance scaling in Weyl semimetal NbAs
Sushant Kumar, Yi-Hsin Tu, Luo Sheng +6
Protected surface states arising from non-trivial bandstructure topology in semimetals can potentially enable new device functionalities in compute, memory, interconnect, sensing,…
Unconventional Resistivity Scaling in Topological Semimetal CoSi
Shang-Wei Lien, Ion Garate, Utkarsh Bajpai +9
Nontrivial band topologies in semimetals lead to robust surface states that can contribute dominantly to the total conduction. This may result in reduced resistivity with decreasin…
Topological Semimetals for Scaled Back-End-Of-Line Interconnect Beyond Cu
Ching-Tzu Chen, Utkarsh Bajpai, Nicholas A. Lanzillo +3
The resistance bottleneck in metal-interconnect scaling calls for new interconnect materials. This paper explores topological semimetals as a potential solution. After reviewing th…
Strong interfacial exchange field in the graphene/EuS heterostructure
Peng Wei, Sunwoo Lee, Florian Lemaitre +9
Exploiting 2D materials for spintronic applications can potentially realize next-generation devices featuring low-power consumption and quantum operation capability. The magnetic e…
Graphene Side Gate Engineering
Ching-Tzu Chen, Tony Low, Hsin-Ying Chiu +1
Various mesoscopic devices exploit electrostatic side gates for their operation. In this paper, we investigate how voltage-biasing of graphene side gates modulates the electrical t…
Spin-Polarized Tunneling Study on Spin-Momentum Locking in the Topological Insulators
Luqiao Liu, A. Richardella, Ion Garate +3
We demonstrate that the charge-spin conversion efficiency of topological insulators (TI) can be experimentally determined by injecting spin-polarized tunneling electrons into a TI.…
Low-Damage High-Throughput Grazing-Angle Sputter Deposition on Graphene
Ching-Tzu Chen, Emanuele A. Casu, Martin Gajek +1
Despite the prevalence of sputter deposition in the microelectronics industry, it has seen very limited applications for graphene electronics. In this letter, we report systematic…
