We present a novel selector made of doped-chalcogenide material. This selector not only achieves low holding voltage (0.2 V) and large on/off ratio (>107), but also exhibits the high on-current density (>1.6 MA/cm2) and large hysteresis window (1.2 V). Besides, excellent selector performances with ultra-low off-state leakage current (10 pA), high switching speed (<10 ns), high endurance (>10...
In this work, tantalum oxide (TaOJ based ring contact Resistive Random Access Memory (RRAM) devices with varying TaOx thicknesses (5, 10 and 15 nm) were demonstrated and evaluated. TaOx layers were deposited using atomic layer deposition and were in contact with a Platinum (Pt) top electrode and Tantalum (Ta) sidewall electrode. RRAM devices with different TaOx thickness were compared to investigate...
The thermal conductivity of nitrogen-doped Ge2Sb2Te5 (N-GST) was analyzed using Frequency Domain Thermoreflectance (FDTR). The thermal conductivity of amorphous N-GST (∼0.15 W/m-K) was not found to change significantly as the nitrogen concentration was raised from 0 at% to ∼6 at%, possibly due to the huge amount of phonon scattering in the disordered films. The thermal conductivity of crystalline...
We present the realization of a novel three-terminal electronic switch using phase-change (PC) chalcogenide material. This device subdivides a single PC switch into a parallel array of three-terminal subvias which are addressed with atomic-force-microscopy cantilever probes. This subdivision reduces the required switching current to acceptable levels. Vias of Ge50Sb50 are demonstrated in this switch...
