Interfacial strong coupling and negative dispersion of propagating polaritons in freestanding oxide membranes
Brayden Lukaskawcez, Shivasheesh Varshney, Sooho Choo +12
Membranes of complex oxides like perovskite SrTiO3 extend the multi-functional promise of oxide electronics into the nanoscale regime of two-dimensional materials. Here we demonstr…
