We demonstrate ultralow leakage current AlGaN/GaN Schottky-barrier diodes (SBDs) based on a 3-D anode contact. In contrast to conventional AlGaN/GaN SBDs, this new device forms a Schottky contact directly to the 2-D electron gas (2-DEG) at the sidewalls of ...
Recently, several emerging technologies have been reported as potential candidates for controllable ambipolar devices. Controllable ambipolarity is a desirable property that enables the on-line configurability of n-type and p-type device polarity. In this ...

Ambipolar devices have been reported in many technologies, including carbon nanotube field effect transistors (CNTFETs). The ambipolarity can be in-field controlled with a second gate, enabling the design of generalized logic gates with a high expressive p ...

Magnetic order in graphene-related structures can arise from size effects or from topological frustration. We introduce a rigorous classification scheme for the types of finite graphene structures (nanoflakes) which lead to large net spin or to antiferroma ...

One of the ways that custom instruction set extensions can improve over software execution is through the use of hardware structures that have been optimized at the arithmetic level. Arithmetic hardware, in many cases, can be partitioned into networks of f ...

Coherent manipulation of spin ensembles is a key issue in the development of spintronics. In particular, multivalued spin switching may lead to new schemes of logic gating and memories. This phenomenon has been studied with atom vapours 30 years ago, but i ...
