"2D hafnium oxide and zirconium oxide chips... material processed directly on top of microprocessors... 1 layer of dielecric is negative capacitance material enabling increased overall capacitance... grown by atomic layer deposition using standard materials/ techniques... tuning balances films at tipping point between ferroelectric and antiferroelectric enabling negative capacitance and polarization by even small electric field... 9X higher energy density, 170X higher power density."
