Title: Electronic properties of single-crystal diamonds heavily doped with boron

Abstract

Single-crystal diamonds with characteristic sizes of 2-7 mm doped with boron in the concentration range 10{sup 19}-10{sup 20} cm{sup -3} have been grown by the temperature gradient method at high static pressures. The temperature dependence of the resistance R of the synthesized single crystals has been measured in the range 0.5 K < T < 297 K. An activated dependence R(T) with an activation energy of about 50 meV is observed in the range from room temperature to T {approx} 200 K. At temperatures below approximately 50 K, the temperature dependence of the conductivity for heavily doped crystals is proportional to T{sup 1/2}, which is characteristic of degenerate semiconductors with a high number of defects.

  • Phase pure cubic boron nitride (c-BN) films have been epitaxially grown on (001) diamond substrates at 900 °C. The n-type doping of c-BN epitaxial films relies on the sequential growth of nominally undoped (p-) and Si doped (n-) layers with well-controlled thickness (down to several nanometer range) in the concept of multiple delta doping. The existence of nominally undoped c-BN overgrowth separates the Si doped layers, preventing Si dopant segregation that was observed for continuously doped epitaxial c-BN films. This strategy allows doping of c-BN films can be scaled up to multiple numbers of doped layers through atomic level control ofmore » the interface in the future electronic devices. Enhanced electronic transport properties with higher hall mobility (10{sup 2} cm{sup 2}/V s) have been demonstrated at room temperature as compared to the normally continuously Si doped c-BN films.« less
  • Using the self-consistent pseudopotential method, we have studied the conducting properties of Si donor states in heavily and orderly doped (GaAs){sub 2}-(AlAs){sub 2} superlattices. The Si donor states are arranged to simulate a two-dimensional-conductor and a one-dimensional quantum-wire structure. We have found that the Si donor states can form one- and two-dimensional conducting channels even in these very-thin-layered superlattices. By analyzing the charge density of the donor states we have also found that the width of the conducting channel is about five atomic layers. In the one-dimensional configuration, the effects of the reduction in dimensionality on the energies and themore » charge distributions of the donor states are presented. The current density is also calculated to show the channeling properties.« less
  • The polarisation absorption spectra of forsterite single crystals grown from a melt containing from 0.015 to 0.97 wt% of chromium are studied. Most of the crystals were grown by the Czochralski method under standard oxidation conditions (1.4-2.4 vol % of oxygen). Some crystals were grown in the atmosphere with a higher content of oxygen ({approx}12 vol %) or in the neutral atmosphere (100% of Ar). Crystals grown from a melt containing more than 0.6 wt % of chromium exhibited the saturation of absorption of Cr{sup 4+} ions. The maximum absorption coefficient of Cr{sup 4+} ions at 1064 nm was {approx}3.2more » cm{sup -1}. The relative content of Cr{sup 3+} ions also increased (approximately by 70% in the range studied) with increasing the doping level. The relative content of Cr{sup 3+} ions in a crystal grown in the atmosphere with a high content of oxygen ({approx}12 vol %) was approximately lower by a factor of 1.5 than that in a crystal grown in the standard oxidation atmosphere.

  • The polarised luminescence spectra of forsterite single crystals grown from a melt containing from 0.015 to 0.97 wt% of chromium are studied. Most of the crystals were grown by the Czochralski method under standard oxidation conditions (1.4-2.4 vol% of oxygen). Some crystals were grown in the atmosphere with a higher content of oxygen ({approx}12 vol%) or in the neutral atmosphere (100% of Ar). The luminescence of Cr{sup 4+} ions excited to the {sup 3}T{sub 2} level at 980 nm and to the {sup 3}T{sub 1} level at 632.8 nm exhibited no quenching over the entire range of crystal doping. Inmore » crystals absorbing above 70% of laser energy, the self-absorption of luminescence of Cr{sup 4+} ions was observed. The reabsorption of luminescence of Cr{sup 3+}(2) ions located in sites of the forsterite crystal with the mirror symmetry occurs stronger because of a greater overlap of the luminescence band of Cr{sup 3+}(2) ions with the absorption bands of Cr{sup 4+} ions. The luminescence of Cr{sup 4+} ions is found to be polarised predominantly along the b axis for any polarisation of exciting radiation. The broadband luminescence of Cr{sup 3+}(2) ions is polarised predominantly along the c axis for all the crystals studied, irrespective of the polarisation of exciting radiation and the oxygen concentration in the crystal-growth atmosphere. The luminescence of Cr{sup 3+}(2) ions polarised along the c, b, and a axes has maxima at {approx}900, 860, and 850 nm, respectively. (active media)« less
  • The changes in hole concentration of heavily boron (B)-doped Czochralski silicon subjected to high temperature rapid thermal anneal (RTA) and following conventional furnace anneal (CFA) have been investigated. It is found that decrease in hole concentration, namely, B deactivation, is observed starting from 1050 °C and increases with RTA temperature. The following CFA at 300–500 °C leads to further B deactivation, while that at 600–800 °C results in B reactivation. It is supposed that the interaction between B atoms and silicon interstitials (I) thus forming BI pairs leads to the B deactivation during the high temperature RTA, and, moreover, the formation of extendedmore » B{sub 2}I complexes results in further B deactivation in the following CFA at 300–500 °C. On the contrary, the dissociation of BI pairs during the following CFA at 600–800 °C enables the B reactivation. Importantly, the first-principles calculation results can soundly account for the above-mentioned supposition.« less
