          This Schedule 13D is being filed by the reporting person in order to
disclose (i) the ownership by affiliates of the reporting person of convertible
preferred stock of the issuer and (ii) the formula pursuant to which the
convertible preferred stock of the issuer held by affiliates of the reporting
person may be converted into the issuer's common stock. The convertible
preferred stock may be fully converted into common stock of the issuer on and
after March 1, 1997.

ITEM 1.   SECURITY AND ISSUER

          This Schedule 13D relates to shares of common stock, $.001 par value
(the "Common Stock"), of SI Diamond Technology, Inc. (the "Issuer") that are
issuable to Nelson Partners, a Bermuda exempted general partnership ("Nelson"),
and Olympus Securities, Ltd., a Bermuda corporation ("Olympus"), upon conversion
of Series E Preferred Stock ("Convertible Securities") held by Nelson and
Olympus. The principal executive offices of the Issuer are located at 12100
Technology Boulevard, Austin, Texas 78727.

ITEM 2.   IDENTITY AND BACKGROUND

          This Schedule 13D is being filed by Citadel Limited Partnership, an
Illinois limited partnership ("Citadel"). Citadel's principal business office is
located at 225 West Washington Street, 9th Floor, Chicago, Illinois 60606.

          During the last five years, Citadel has neither been convicted in a
criminal proceeding (excluding traffic violations or similar misdemeanors) nor
party to a civil proceeding of a judicial or administrative body of competent
jurisdiction pursuant to which Citadel either became subject to a decree or
final order enjoining future violations of, or prohibiting or mandating
activities subject to, federal or state securities laws or was found in
violation of federal or state securities laws.

ITEM 3.   SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

          Citadel is the managing general partner of Nelson and the trading
manager for Olympus. The funds used for purchases reported herein are from the
accounts of Olympus and Nelson. Citadel has no beneficial ownership interest in
any of the funds or other property of Olympus or Nelson, except for Citadel's
interest as general partner of Nelson.

          Nelson and Olympus funded $3,000,000 to the Issuer to acquire
Convertible Securities pursuant to Subscription Agreements between each of
Nelson and Olympus and the Issuer as of January 4, 1996 ("Funding Date").

ITEM 4.   PURPOSE OF TRANSACTION

          The purchases reported herein were made as an investment. Citadel may,
in the future, recommend or make additional purchases or sales of the subject
Securities on behalf of Nelson or Olympus.

          Citadel has no present plans or proposals which would relate to or
result in transactions of the kind described in paragraphs (a) through (j) of
Item 4 of Rule 13D-101 of the Securities and Exchange Commission. However,
Citadel reserves the right to adopt such plans or proposals, subject to
applicable regulatory requirements, if any.

ITEM 5.   INTEREST IN SECURITIES OF THE ISSUER

          (a)  By reason of its serving as managing general partner of Nelson
               and trading manager of Olympus, Citadel may be deemed to be the
               indirect beneficial owner of (i) the Convertible Securities and
               the shares of Common Stock into which the Convertible Securities
               are convertible and (ii) the Common Stock, in each case, held by
               Nelson and Olympus. As of the date for the filing of this
               statement, Nelson and Olympus collectively own Convertible
               Securities for which they originally paid $2,720,000 ("Stated
               Value") and 11,254 shares of Common Stock.

               As of any date ("Conversion Date") all or a portion of the
               Convertible Securities may be converted into the number of shares
               of Common Stock determined by dividing the Stated Value of such
               securities (plus an amount equal to 8% interest on the Stated
               Value of such securities from the Funding Date) by a conversion
               price ("Conversion Price"). The Conversion Price is equal to the
               lesser of (i) $3.00 and (ii) 85% of the average closing bid price
               (as reported by NASDAQ or such other market or exchange as the
               Common Stock is then traded) of the Issuer's Common Stock for the
               five trading days immediately preceding the Conversion Date.

               If the Company's Common Stock is trading at a price less than
               $3.53, the Conversion Price will fluctuate depending upon the
               closing bid price of the Issuer's Common Stock. As a consequence,
               the number of shares of Common Stock into which the Convertible
               Securities may be converted, and consequently the number of
               shares of such securities which Citadel may be deemed to
               beneficially own, may fluctuate on a daily basis based solely on
               the Common Stock's market price and without any action taken by
               Citadel, Nelson or Olympus.

               As of the date for the filing of this statement, by virtue of its
               status as the managing general partner of Nelson and the trading
               manager for Olympus, Citadel may be deemed to be the beneficial
               owner of 2,413,476 shares of Common Stock representing 15.54% of
               the Issuer's Common Stock (based on (i) 13,125,083 shares of
               Common Stock issued and outstanding as set forth in the Issuer's
               most recently filed 10-QSB and (ii) a Conversion Price equal to
               $1.22).

<PAGE>
 
     (b)  Citadel has the sole power to vote and the sole power to dispose of
          the Convertible Securities, the Common Stock into which the
          Convertible Securities are convertible and the Common Stock held by
          Nelson and Olympus on behalf of each of Nelson and Olympus.

          have been effected during the 60-day period ending December 30, 1996:
