Impact of irradiation conditions on the magnetic field sensitivity of spin defects in hBN nano flakes
Saksham Mahajan, Ravi Kumar, Aferdita Xhameni +8
We study centres generated by helium focused ion beam (FIB) irradiation in thin (70 nm) hBN nanoflakes, in order to investigate the effect of implantation…

Modulation of superconductivity across a Lifshitz transition in alternating-angle twisted quadrilayer graphene
Isabelle Y. Phinney, Andrew Zimmerman, Zeyu Hao +5
We report electric field-controlled modulation of the Fermi surface topology and explore its effects on the superconducting state in alternating-angle twisted quadrilayer graphene…
