Carbon nanotube–based MOSFETs doped using a scalable technique

In recent years, electronics engineers have been trying to identify materials that could help to shrink the size of transistors without compromising their performance and energy efficiency. Low-dimensional semiconductors, solid-state superconducting materials with fewer than three spatial dimensions, could help to achieve this. Among low-dimensional semiconducting materials that have been found to be particularly promising for reducing the length of gates inside transistors are one-dimensional (1D) carbon nanotubes. Nonetheless, most proposed strategies to dope these materials and control the polarity inside them are not compatible with existing large-scale electronics production methods.

Flotsam and jetsam.

My obsessive checking of classified ads can lead to darkish moments. I sold my Sony 2251 Turntable a long time ago. It is good and rare and I have seen mine pop up on rolling seascape of on-line listings twice. Both were oh dear moments. What went wrong? Has it failed? Is it not in a happy home?

The first was the person I sold it to apparently having a bad turn in his health and offering it for a lot less than he paid for it. I almost got in touch, but no my time with it was past. There are a couple out there and they command good prices. I hoped it was to go to a good new home.

Recently I saw it again. Actually I saw a photo of it as just the tonearm was for sale. It was the Grace 707 from back in the day of high compliance 45khz cartridges for quadraphonic. I did not see it as a parting out, but the Sony originally had an SME 3009 tone arm and the arm board was drilled out for that. If an aficionado had it they may have recognized that and wanted to restore it to an SME. At least that is the story I tell myself. Why else sell just the tonearm?

I have to be really careful. My system has a nice balance and I like where its at. My one itch is a MOSFET power amp. At least I tell myself that. Oh and if a Beogram 4002 came up for a good price I would be hard pressed to resist. I recently saw a Mosfet amp for sale for a hot number. The company that made it rode high for awhile, but is now gone. I have not been able to find a definitive schematic as I always look at those.

I am not mentioning where or the brand as I do not want someone grabbing it before I have convinced myself to not get it. This always makes me feel doubt. Still working on that.

I found photos of the interior which evolved over a few years. Apparent that the large power supply is shared by both sides which is a strike against it. There is lots of room to add capacitors, and a bridge rectifier which is a tick in the good side box. But apparently there is a large circuit board on the power supply on later versions for mysterious reasons. Regulation? Some kind of protection system? If I could get a schematic that described it that would really help. If I bought it I would have to split the power supply as that does really help the image clarity.

And if you dig back through the old day reviews as I do you may find reference to FET haze. I assume it is rather like tube haze and FETs are always being compared to the vacuum tube. Vacuum tubes do add something not in the recording. Call it haze or mist or space whatever it is not quite right.

Audiophile neurosis.

My ARC preamp signal path is all FET where it is not a 6DJ8 tube. That works fine for me.

Old school transistors are still used, and every mosfet amplifier I have looked at still has those in critical places. And there are many respected power amps with no FETS anywhere inside. See I have almost convinced myself.

Le transistor MOSFET

Le transistor MOSFET, ou "Metal-Oxide-Semiconductor Field-Effect Transistor", est un type de transistor largement utilisé dans l'électronique moderne. Il joue un rôle crucial dans l'amplification et la commutation des signaux électriques. Grâce à sa capacité à contrôler le courant avec une tension très faible, le transistor MOSFET est devenu un composant essentiel dans les circuits intégrés, les alimentations à découpage, et de nombreux autres dispositifs électroniques.

Le principe de Fonctionnement

Le MOSFET fonctionne selon le principe du champ électrique. Il possède trois électrodes : la source (S), le drain (D) et la grille (G). La grille est séparée de la zone de conduction par une fine couche d'oxyde, ce qui lui confère une très haute impédance. Lorsqu'une tension est appliquée à la grille, elle crée un champ électrique qui modifie la conductivité entre la source et le drain. Cela permet au transistor MOSFET de fonctionner comme un interrupteur ou un amplificateur.

Les différents types de MOSFET

Il existe principalement deux types de MOSFET :

MOSFET à canal N : Dans ce type, le courant circule principalement à travers des électrons. Ils sont généralement utilisés pour des applications nécessitant une vitesse élevée et une faible résistance.

MOSFET à canal P : Dans ce cas, le courant est transporté par des "trous" (lacunes d'électrons). Ils sont souvent utilisés en complément des MOSFET à canal N pour former des circuits complémentaires (CMOS).
