Embodiments of the invention are directed to pelletized synthetic gypsum and methods and systems for producing pelletized synthetic gypsum. An apron assembly collects drill cuttings and deposits such cuttings on a central rotor having multiple distinct chambers. A liquid metal switch is contained within the switching channel. In one embodiment of the present invention, the first gate dielectric stack includes a first high k dielectric and an alkaline earth metal-containing layer or a rare earth metal-containing layer, while the second high k gate dielectric stack comprises a second high k dielectric.
