1 Introduction Hydrogen-terminated diamond surfaces exhibit a number of intriguing electronic properties such as a negative electron affinity,[1] conductivity via the formation of a surface-confined 2D hole gas (2DHG),[2] and sensitivity of the hole density/surface potential to solvated ion concentrations and/or pH.[3, 4] High quality hydrogenated surfaces can provide a direct coupling between charge at the diamond surface and the electrostatic environment within the shallow bulk material...

It augurs well for the EU that efforts are now being made to find common solutions, Le Soir writes approvingy: “Macron seems to have regained his composure and called on Monday for a European mobilisation: cap the price of Russian gas, create a European levy [excess profits tax] to aid member states, introduce solidarity bartering 'French gas for German electricity' and joint purchases of the sort that worked well with vaccines, and all this with thermostats set at 19 degrees in French homes.
