Methods, systems, and devices for composite electrode material chemistry are described. A memory device may include an access line, a storage element comprising chalcogenide, and an electrode coupled with the memory element and the access line. The electrode may be made of a composition of a first material doped with a second material. The second material may include a tantalum-carbon compound. In some cases, the second may be operable to be chemically inert with the storage element. The second material may include a thermally stable electrical resistivity and a lower resistance to signals communicated between the access line and the storage element across a range of operating temperatures of the storage element as compared with a resistance of the first material.

Various implementations include a device for deposition of conformal coatings. The device includes a powder container, a connecting rod, and a crankshaft. The powder container has a first side configured to contain a powder and a second side. The connecting rod has a first end directly hingedly coupled to the second side of the powder container and a second end. The crankshaft has a longitudinal axis, a main shaft portion extending along the longitudinal axis, and a cam portion radially offset from and rotatable about the longitudinal axis. The second end of the connecting rod is directly rotatably coupled to the cam portion. Rotation of the crankshaft about the longitudinal axis causes the second end of the connecting rod to rotate about the longitudinal axis, causing the powder container to linearly oscillate between a first position and a second position.
