Spontaneous time reversal symmetry breaking at individual grain boundaries in graphene
Kimberly Hsieh, Vidya Kochat, Tathagata Biswas +8
Graphene grain boundaries have attracted interest for their ability to host nearly dispersionless electronic bands and magnetic instabilities. Here, we employ quantum transport and…

Optimising Graphene Visibility in van der Waals Heterostructures
Thanmay S. Menon, Simli Mishra, Vidhu Catherine Antony +8
Graphene constitutes one of the key elements in many functional van der Waals heterostructures. However, it has negligible optical visibility due to its monolayer nature. Here we s…
