... profound impact on the conductivity. As an example of the extreme sensitivity of the con- ductivity of SiNMs to surface chemical condition, we describe in this paper t he replacement of the surface oxide ... complete passivation of surface states by H (including the “ poisoning” of the clean -surface bands produced by the 2 × 1 reconstruction) [2,3]. If on...

... consists of an emitter and a nanotip. The emitter is initially in the ground state jgi and the dipole moment p of the emitter is parallel to the axis of the nanotip. Under the action of the control field ... transparent depending on the gate field containing none or one single- photon. Thus, the presence or absence of a single incident photon in a ‘gate’ field is...

... 1. 13q14.3 deletion The most common lesion in CLL is chromosome 13q14.3 deletion, occurring in half of the cases [4]. The deletion is often interstitial and can be homozygous in up to 15% of the cases ... 90% of patients [9]. Only a fraction of the events are balanced translocations, whilst the vast major- ity of them are unbalanced translocations (see below), determinin...
