Electric Polarity

Phase-change random access memory (PCRAM) is widely regarded as one of the most promising candidates to replace Flash memory as the next generation of non-volatile memories due to its high-speed and low-power consumption characteristics. Recent advent of the blade-type PCRAM with low programming current merit further confirms its prospects. The thermoelectric effects existing inside the PCRAM devices have always been an important factor that determines the phase-transformation kinetics due to a fact that it allows PCRAM to have electric polarity dependent characteristics. However, the potential physics governing the thermoelectric effects for blade-type PCRAM device still remains vague. We establish a three-dimensional (3D) electro-thermal and phase-transformation model to study the influences of thermal boundary resistance (TBR) and device scaling on the thermoelectric effects of the blade-type PCRAM during its “RESET” operation. Our research shows that the presence of TBR significantly improves the electric polarity-dependent characteristics of the blade-type PCRAM, and such polarity-dependent characteristic is found immune to the scaling of the device. It is therefore possible to optimize the thermoelectric effects of the blade-type PCRAM through appropriately tailoring the TBR parameters, thus further lowering resulting power consumption.

Intrinsic Thermal Conductivity

In the past decade, the very high intrinsic thermal conductivity of a carbon nanotube (CNT) has been successfully unveiled through experimental studies, but the thermal boundary resistance (TBR) between a CNT and ambient material still remains unclear. Some analytical and molecular dynamics studies have been reported on the TBR between a CNT and a surrounding material but there is no reliable experiment method to quantitatively investigate TBR between a CNT and a solid surface because of technical difficulties.
