The Massachusetts Institute of Technology (MIT) has discovered that pure crystalline carbon--graphene--sandwiched between two ferroelectric layers results in devices with built-in memory that operate in the terahertz range, potentially opening the door to next-generation applications: R. Colin Johnson @NextGenLog
Terahertz optical memories made by sandwiching high-mobility graphene between two layers of ferroelectric materials could boost density by 10-times. Further Reading
