Molten silicon is not a semiconductor, and has no commercial use, although because of the high heat of fusion, it has been considered as a heat storage medium. The Hquid (molten) siUcon properties summarized in Table 6 are nevertheless of importance because these affect single-crystal growth, an operation through which essentially all semiconductor-grade siUcon must pass. 

The material known as bouncing putty is also a silicone polymer with the occasional Si—O—B group in the chain, in this case with 1 boron atom to about every 3-100 silicon atoms. The material flows on storage, and on slow extension shows viscous flow. However, small pieces dropped onto a hard surface show a high elastic rebound, whilst on sudden striking they may shatter. The material had some use in electrical equipment, as a children s novelty and as a useful teaching aid, but is now difficult to obtain.

An additional asset of both donors in silicon and NV centres is that nuclear spins, of 31P in the former and of N and neighbouring 13C in the latter, can be employed as long-term storage quantum memories [63], or even to build multiple qubit registers [22, 67].
